78.7.1 - editing single entry of recurring sequence changes calendar colors and restart loses single entry change
Running Thunderbird on Ubuntu, using operating system color scheme. Prior to upgrade to 78.7.1, calendar background was white, with muted colors for weekend, current day.
Two issues after upgrade:
1 - edit a single entry of a recurring sequence (changing the day); saving the change causes the background color to change to black, with purple for saturday and dark olive for sunday (not my idea of good colors, and definitely not what I want) [ just encountered a second way of causing the calendar color change - start Thunderbird, calendar shows operating system color scheme; change focus to another window then select thunderbird - colors change to black/purple/olive ]
2 - restarting thunderbird restores the operating system color scheme for calendar but the change to the single entry of the recurring series is lost (reverts to the recurring series value)
Any ideas?
