None.

Summary of the issue:

When inside a list in a contentEditable on the web, cursoring from one listItem to the next does not provide any speech feedback telling you that you are in a new listItem. In browse mode, at least you'd probably have a bullet or number which would alert you to the fact, but in contentEditables, usually the cursor skips over the bullet.
Take this example in Chrome / Firefox.

data:text/html,<div contenteditable="true"><ul><li>This is bullet one</li><li>This is bullet two</li></ul></div> 

NVDa should speak "list item" when cursoring with left and right arrow from the first to the second, or the second to the first. Note that we should not do this when moving by line, nor should we say "out of list item" as that is somewhat redundant.

Description of how this pull request fixes the issue:

• TextInfo.getPresentationCategory now takes an 'extraDetail' keyword argument.
• TextInfo.getPresentationCategory treats ROLE_LISTITEM as a marker (rather than layout) if extraDetail is true.
• speech.getControlFieldSpeech now passes its extraDetail argument to TextInfo.getPresentationCategory.
• Provided an implementation of _getcontrolFieldForObject on MozillaCompoundTextInfo, which sets the 'uniqueID' key on the controlField using IAccessible2 uniqueID if available. This ensures that controlFields from different objects (no matter if they have the same role and other attributes) are treated as different controlFields when calculating entering / exiting controlFields in speech. Without this change, entering a new listItem would still say nothing as both controlFields look identical.

these changes together mean that NvDA will now announce 'listItem' when moving into a listItem when navigating by character or word.

Testing performed:

With the above testcase in Firefox / chrome: in focus mode ensured that pressing left and right arrow crossing the list item boundary speaks "list item" but not "out of list item" and ensure that moving by line does not announce "list item".

Known issues with pull request:

When arroing into a list from the outside with the left or right arrows, NVDA will say "list list item". Technically this is correct, but perhaps a little redundant. However, as this only happens when moving by word or character, I don't believe this is too annoying, weighing it up against what this does fix.

Bug fixes:

• When arrowing by character or word from one list item to another in editable content on the web, entering the new list item is now announced.
