Attachment: Bug 1974208: Disable failing test r=dimi

Comment 25

[Simon Friedberger [:simonf]]

I don't know why the internal state of the EventStateManager is broken and I probably won't have time to dive into that soon. Therefore, I am disabling the test and unassigning myself.

(In reply to Simon Friedberger (:simonf) from comment #25)

I don't know why the internal state of the EventStateManager is broken and I probably won't have time to dive into that soon. Therefore, I am disabling the test and unassigning myself.

OK, but now this bug is closed and there is no link to any other bug to figure out the underlying problem? Olli, any ideas what is/was going wrong here?

Comment 32

[:Gijs (he/him)]

For context, I saw this on a trypush whose parent is too old to have the patch from here; unfortunately pernosco still couldn't repro the failure.

Simon, I don't suppose you filed a follow-up ticket and just forgot to link it here? :-)

Comment 33

[Simon Friedberger [:simonf]]

Ah, sorry! I did indeed not file any bugs or link them here, I just asked on Matrix and left it to the other bugs:

• bug 1792061
• bug 1780802
