1648145 - Main Thread Title Doesn't Change in Sources Tree

Status: RESOLVED FIXED

(DevTools :: Debugger, defect)

1. Go to https://davidwalsh.name
2. Open debugger -- see "David Walsh ...." at the top of the sources tress.
3. Click a link to any blog post
4. ERROR: Main thread title DOES NOT CHANGE (articles are swapped via AJAX, so maybe reasonable that the title doesn't change)
5. Navigate to https://facebook.com
6. ERROR: Main thread title is "David Walsh ..."

It appears that the main thread title never changes in the sources tree. I believe this is because that the thread name is set when initially attached but doesn't update upon navigation.

I don't know that setting the main thread name to the page title is a good solution. Since document.title can change a page title within JavaScript, and someone could update that every 2 milliseconds, updating page titles could either not work or just bog down the debugger.

Good call. We should probably use 'Main Thread' or something generic like that.
