1279541 - Developer Tools Hang on Breakpoint during onblur

Status: RESOLVED WORKSFORME

(DevTools :: Debugger, defect, P3)

Description

[Eric Brandel]

Attachment: proof of concept

User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36

Steps to reproduce:

Adding a breakpoint in an onblur event causes the current tab to become unresponsive (unable to click anything in the tab, including the Click To Resume (play) button). When the tab and/or browser loses focus, the tab will then become responsive again.

In the attached example, adding a breakpoint at line 10 exhibits the behavior.


Actual results:

The browser tab hangs.


Expected results:

The browser tab should not hang.

At first glance, this sounds like a nested event loop problem.
