What were you doing?

(see video)

  1. Inspected event location in!/viewer
  2. Set a Breakpoint somewhere in
  3. Set a logpoint on the BP

What happened?

Debugger jumps and afterwards does not show any added breakpoints in the gutter.

After the STR, breakpoints are broken throughout Debugger, any file, until it gets closed and re-opened.

After the STR, jumping to sources from the events bubble is also broken and jumps to the wrong line.

What should have happened?

Logpoints and Debugger work.

Priority: -- → P2

P1 until we have more insights into this.

Logan, could this be related to the column bp work?

I started looking into this and noticed that the original file track_panel.ts works fine, ...

okay - so what was happening was that we were showing the conditional panel at the original line (177) and not letting you do anything while it was open...

this is a pretty easy fix

hmm, i'm a bit confused my new patch is on top of beta, but the old would probably apply too.

Grafting the patch from central should be fine, I think.

Is this something you would like to see uplifted to release?

Flags: needinfo?(jlaster)

I don't think this is necessary. I have a pretty high threshold for uplifting to release.
