GNOME Bugzilla – Bug 753702
Changing mail composer to plaintext mode and back to HTML mode changes the font family
Last modified: 2015-08-25 10:57:14 UTC
Type some lorem ipsum into the HTML mail composer, switch to plaintext mode then switch back to HTML mode... notice that the text is now using a larger, monospace font, instead of the default sans serif font. Problem is, you can't reset it to not be monospaced, the text paragraph style is already "normal" (not "preformatted") and there is no font family control. This apparently also affects the resulting sent mail. The pre-webkit version of the composer didn't use to do that, IIRC.
Thank you for your bug report. The issues was fixed with commit 8aa930e0634b22afa38753816be824d7b1622140 in the master branch for Evolution 3.17.91+.
