This looks to be frequent, as it can be seen here. After some retriggers and backfills looks to be related with Bug 1855910.

Hello Alexandre! Could you please take a look at this?

Thank you!

I'm investigating, but having a hard time addressing it.

Attachment: Bug 1839857 - [devtools] Wait before clearing breakpoints.

Clearing the breakpoints after the reload pretty printed source is complex.
We have to ensure waiting for the full processing of the new pretty printed source,
otherwise the synchronization of the breakpoints on that new source may be done
after of the clearance of all the breakpoints.
