There was a problem hiding this comment.
Thanks for taking the time to make this PR @susanwere!
I've left some comments, because I think we need to go in a slightly different direction here. Let's try to ensure that:
- Any behaviour we add is well tested.
- We don't rely on the user agent to determine which behaviour we use.
Given the above two, I would be happy to re-review this if it:
- Retains the tests that are in place (even if they're altered).
- Adds new tests (to cover the new edge cases we've discovered).
- Removes the user agent sniffing and uses feature detection instead.
If you need any assistance with this please let me know, and I'd be happy to pair.

👋 This is a second attempt to fix https://github.com/github/issues/issues/5429
After merging this PR in master we realised that the fix didn't solve the issue. I did a second check and found the following issue which causes the bug.
While creating the tree walker, we specified that we only want to show nodes that are elements. This works well in the chrome browser because it generates
spanfor texts that don't have a html tag as shown in the screenshots below. For Firefox, texts that don't have a html tag are skipped because they are not identified as elements thereby causing the bug.The fix is to SHOW_ALL nodes for firefox and only SHOW_ELEMENTs for chrome.
