Bug 159525

Created attachment 192347 [details]
HTML paste from Word in Free Clipboard Viewer

This is a followup to bug 157363

In cases when an external app (in our cases: MSO apps) puts copied content in HTML and RTF format to the clipboard, it could be useful to have an option to prefer the HTML format as default paste format over RTF, as some apps (such as MSO) may put more content into HTML compared to RTF.

1. Open attachment 192289 [details] from bug 159478 (but really any complicated document should do) in Word
2. Copy everything
3. In PowerPoint go to Paste - Paste Special
4.a Insert the content as HTML
-> There is a table pasted. The font formatting is however lost (e.g. FAX is not in large bold font)
4.b Insert the content as RTF
-> No table, only text is pasted. Font formatting is retained.

So both source formats have pros and cons, it may make sense to:
(1) make it configurable via a config key that can be tweaked per deployment.

(2) Another option may be to actually look inside the clipboard content and check for something like this:
<meta name=Generator content="Microsoft Word 15">
<meta name=Generator content="Microsoft PowerPoint 15">
and if this is found in the HTML clipboard content, prefer this automatically.
