empty tree view and code view in Firefox 52 and chrome 56 on windows 10 64 bit

[stevefaulkner]

works fine in IE 11 not in firefox or chrome

hmm, seems to work for me in Chrome 57/Win 10/64bit

howver yes, in firefox i get a treeview with "" in it

I got the following return values.
Chrome(get_innerHTML function) returned failure code: 0x80004001(E_NOTIMPL)
Firefox(get_accChild function) returned failure code: 0x80070057(E_INVALIDARG)

And, I used and tried an old version of Firefox.
Firefox 50.0.2: S_OK
Firefox 51.0.1 and 53.0: E_INVALIDARG
Could you ask the mozilla team about this result of Firefox?

@jun325 I have asked 2 friends who are Mozilla acc engineers.

[stevefaulkner]

filed a bug on firefox after discussion with Alex and marco https://bugzilla.mozilla.org/show_bug.cgi?id=1363026

found there is same issue with inspect.exe

@jun325

can you review this comment on the Firefox bug https://bugzilla.mozilla.org/show_bug.cgi?id=1363026#c8

They have marked as wontfix and described an alternative method for accessing the information.

[dbolter]

Will the alternative method work for you?

Thanks @stevefaulkner
I have just uploaded the new version. 225fb63

[patrickhlauke]

225fb63 does indeed fix this (tested in Win10)

On Chrome 63 on Windows 10, the tree is populated, but the HTML code isn't.

When I was investigating the cause of this issue, I found this source code(https://cs.chromium.org/chromium/src/content/browser/accessibility/browser_accessibility_com_win.cc?l=1381), and I tested HTML5+Mathml(https://www.tutorialspoint.com/html5/html5_mathml.htm).
Please see the screenshot below.
