Explain the problem.
If I convert to ODT the following simple markdown document

### Title title title title

Text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text:

$$μ_1 = 0,8\ \left(\frac{60{°}-α}{30{°}}\right) = 0.64$$

using the command

pandoc test.md -s --self-contained -o test.odt

I get the equation wrongly placed between two lines of text, while it should be after the end of text.

see https://stackoverflow.com/q/70472898/694360

Pandoc version?

I'm using

pandoc 2.16.2 Compiled with pandoc-types 1.22.1, texmath 0.12.3.2, skylighting 0.12.1, citeproc 0.6, ipynb 0.1.0.2

under Ubuntu 20.04.3 running on Windows Subsystem for Linux (WSL 2).

the XML that is generated (in content.xml when unzipping the odt file) is:

<text:p text:style-name="First_20_paragraph">Text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text:</text:p>
<text:p text:style-name="Text_20_body">
  <draw:frame draw:style-name="fr2" text:anchor-type="paragraph">
  <draw:object xlink:href="Formula-0/" xlink:type="simple" xlink:show="embed" xlink:actuate="onLoad" /></draw:frame>
</text:p>

so seems like the formula is just places as some sort of floating object? what do you think it should be?

The ODT structure seems correct, so is it a LibreOffice bug? I also noticed that editing inside Libre Office and switching to 'as char' anchor type, moves the anchor from the end of the text to the middle of the text, which is not correct in my opinion.

Changing the code so to use anchor-type="as-char" and centering the paragraph of the equation would solve the issue, but I don't know if that would be the right thing to do.

A non-optimal workaround is to add a line break just before the equation

<br/>$$equation$$

knowing that the added line-break will be oddly placed after the equation.

Update

I discovered that the issue show up only if the equation is too high. In fact, it doesn't show up with $$\frac{1}{2}$$, but it does with $$\frac{1^2}{2^A}$$.

I asked about this issue on LibreOffice forum and I got some hints which are beyond my knowledge, but hopefully clearer to some pandoc contributor:

I opened this in MS Word and the equation displayed after the text.

Setting anchor-type to frame gets the vertical position right, but loses the centering.

nopria commented Dec 28, 2021

Setting anchor-type to "character" also fix the vertical placement. Since the standalone equation (i.e. "$$...$$") is placed in a dedicated paragraph, why not center it? Stand alone equations usually are centered, isn't it?

I think I've fixed this -- can you test?

Sorry, I can't test, I tried to install the master branch compiling it from source but after a couple of times kicking me out of WSL2 without errors during stack setup (which after some retries finally completed) I'm stuck at stack install with an error ending with:

Maybe that was above the capabilities of Windows Subsystem for Linux.

Hm. Not sure, the part you quote only contains a warning, so the true error must be further up (it says it concerns commonmark-pandoc). Scroll up further to find it.

Not sure what is going on there, but I don't think it's a problem with the library itself; rather, a problem with your stack setup. You could try deleting (better, moving) your ~/.stack directory and trying the build again.

stack setup aborted 3-4 times kicking me out of WSL (without any message) before completing on retry, so I guess there was some problem with it. However, running again stack setup says only stack will use a sandboxed GHC it installed, without errors or warnings, and running again stack install gives the same error above.

By the way, if you already tested the fix it's fine for me, I'll wait for next pandoc release 2.16.3.

It should be in a nightly soon. (You could also try using cabal install.)
