Diacritics stripped when posting Facebook comment

[1ec5]

As reported on AMO, #105 recently regressed, probably due to a change Facebook made. Submitting any text field on a profile page or chat box strips the text of any diacritics entered since the last plain character.

This issue does not reproduce with system input methods in Firefox on OS X; however, Firefox gets very confused about where the keyboard focus is, suggesting that Facebook is doing something unusual with the textbox.

Possibly related to kimkha/avim-chrome#18.

Facebook also strips the diacritics as soon as you focus some other element on the page then refocus the textbox, or as soon as you switch tabs or windows and back.

At this point, the most likely culprit is that the React component that manages the contenteditable box (react-composer) is overwriting the box’s contents with the value of a property in the component’s model.

The component tree looks something like this:

<ComposerStatusAttachmentMentionsInputWithTagExpansionContainer>
<ComposerStatusAttachmentMentionsInputContainer>
<ReactComposerStatusAttachmentMentionsInput>
<MentionsInput>
div
<AbstractMentionsTextEditor>
div
<n>

AVIM once again works in Facebook and Messenger as of v5.7.0b2, which is in the beta channel. Barring complications, I’ll publish to the release channel in a few days.
