Code being injected by toolbar into Visual Editor

[hexified]

Morning.

I've come across an issue where if a user has Microsoft Lync installed on their machine, that if the browser has the 'link to call' and 'lync browser helper' tool bars enabled, their browser automatically inserts a telephone icon and related span tag into the visual editor that breaks the editor.

Users are not able to save their changes after this code has been inserted and it happens automatically as a phone number is typed in. But you can publish articles with the injected code without saving to draft.

Thanks @hexified for the bug report.

It seems this is a shortcoming in the Lync Web App plug-in. It shouldn't be touching/changing anything inside contentEditable areas like the TinyMCE iframe. Perhaps there is a setting in there somewhere to stop that behaviour? If not, I'm not really sure what we can do. This could probably be fixed by a "filter" on saving in TinyMCE, but it will be best if it is fixed in the web app.

Does the same happen with Skype for Business Web App that replaces Lync Web App? If yes, could you report that to the authors.

For now perhaps the users can try using incognito mode/tab or another method of temporarily disabling these toolbars while accessing WordPress admin.
