Status: RESOLVED FIXED

(DevTools :: Debugger, enhancement, P3)

Description

[Jason Laster [:jlast]]

Steps:

1. Open Editor/Tabs.js
2. Find the line in updateHiddenTabs that has hiddenTabs.find(tab => tab.id == selectedSource.id)
3. Click to add a breakpoint

AR:
The second column breakpoint is enabled.

ER:
The first one would be enabled.

The cause of this is most likely that the second breakpoint is actually the first one, in the generated file. We are likely sorting based on generated position, rather than based on the order for the file you are actually viewing.

It seems wrong that the breakpoints are ordered differently in this case, so I'll be filing a separate bug for that, perhaps the sourcemap is just bad in this case. Filed in #8093
