Slim template regression with v3.4.5

[ledermann]

What version of Tailwind CSS are you using?

v3.4.5

What build tool (or framework if it abstracts the build tool) are you using?

postcss-cli 8.4.39 (but IMHO not relevant here)

What version of Node.js are you using?

v20.9.0

What browser are you using?

Not relevant

What operating system are you using?

macOS (but not relevant)

Reproduction URL

Because the bug belongs to Pug or slim, play.tailwindcss.com cannot be used to build an example. I will send a PR to fix, please don't close this issue.

Describe your issue

After upgrading my Rails application (using Slim templates) to Tailwind CSS v3.4.5, I found a regression that some classes are not generated anymore. Example:

.bg-green-300.2xl:bg-red-300
  '(Look mom, no closing tag!)

The class 2xl:bg-red-300 is missing. It seems this happens because #13959 uses an invalid number check.

Stay tuned, I'm working on a PR to fix this.

fix released in v3.4.6 -- thanks!

I have a similar problem (in haml) with the class xl:col-span-2 in the line .xl:col-span-2.xl:pr-8. With 3.4.5 and 3.4.6 the col-span-2 class is not extracted. Can open a new issue, if required.

@Skulli I just tried your example in the test suite of tailwindcss v3.4.6 and it works fine. Both classes are extracted. So it seems to be a different thing, maybe your example is not complete. I suggest creating a new issue with a minimal failing example.
