libpurple sipe messages from latest MS Office/Lync/Skype for Business include font information

[mail@…]

I've started seeing this as colleagues are getting the latest MS Office/Lync/Skype for Business suite. This is an example of two people saying "Hello". Using Finch/libpurple and pidgin-sipe I don't have this problem. I guess bitlbee needs to hide this information. I've tried the latest version of bitlbee from git and still see this issue.

That's a <style>, it removed the tags and kept the content. It's silly. I guess strip_html could also nuke the <!-- -->

Yes that might be a good solution, but it doesn't strip them currently with strip_html as true.

I think my colleagues have had Windows updates recently, and now with "strip_html true" I do not see any font info. With "strip_html false" I see some, but not as much as before.
