Since upgrading to Plasma 6.7 in openSUSE Tumbleweed, new mail notifications from Thunderbird no longer disappear when I click the Delete button in the notification (sometimes I can tell immediately from the subject line that it is of no interest). The delete action does happen - that is, the email is deleted. But the notification stays present on screen, at least while the mouse is hovering over it.
I’m not sure if this is a Thunderbird problem or a Plasma problem, but it started when Plasma upgraded to 6.7 and Thunderbird was still the same version.
I’m running the Flatpak version of Thunderbird, if that’s relevant, version 152.0. With the “Use the system notification” setting ticked.
Is this a Plasma bug maybe?
