Thunderbird calendar notifications close themselves

[WaltZ]

I was sitting and staring at my computer when a Thunderbird calendar notification decided to close itself and poof! it was gone.

I don't know if this is related or not, but dismissing a single notification when multiple are shown will close them all.

Thank you for your bug report. Which version of Thunderbird are you using and which package format (deb or snap)?

Could you take a screenshot showing the type of notification you are talking about?
