As part of the QA efforts in bug 1536453 around PowerPoint, QA has found two issues with Word that are related:

  • CMD+A selects the text but shifts the focus out of the word_document, user cannot add extra text after this form of selection
  • After a text is added double clicking on it and writing something else doesn't replace the string but instead adds the new text to the existing one(happens with a flicker)

They could be fixed by adding to the dom.keyboardevent.keypress.hack.use_legacy_keycode_and_charcode pref.

Filing a separate issue here so we can track those independent from thee PowerPoint issue, which has been addressed by a Normandy rollout, and the matching pref-patch is already in Nightly.

I am not sure if we should be tracking these issues for 66. While they are a regression, they do not completely break the application, unlike the PowerPoint issue. We could also decide not to use the pref to hotfix those cases, and wait for Microsoft to respond.

Has these issues been reported to Microsoft? Since these are web page issues, not implementation issues.

Has these issues been reported to Microsoft?

We have a thread about the issues in bug 1536453, which have the same cause (bug 1502795 reaching Release). The Word issues were not known initially, but I just added them to the thread. :)

QA has filed bug 1538652 and bug 1538651 with more details. Let's mark this one as a dupe.
