Web Inspector: Heap profile isn't shown if profiles are selected in a particular order

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

What steps will reproduce the problem?
1. Open any page (say, google.com)
2. Open DevTools, go to "Profiles" page.
3. Take 3 heap snapshots; "Snapshot 1" will be selected automatically
4. Select "Snapshot 3" -- its contents will never be shown (although, clicking on "Snapshot 2" shows the contents).

If in step 4., instead of jumping to "Snapshot 3", one will select "Snapshot 2", and then "Snapshot 3", all snapshots will be shown.

Seems you'll need someone who knows the inspector to look.  You can use webkit-patch suggest-reviewers to find appropriate reviewers, or pass --suggest-reviewers to webkit-patch upload to have them automatically CC'd when you post a patch.

Nevermind.  With 10 people already CC'd you should be fine. :)  I clearly started at the wrong end of the review queue.

[Mikhail Naganov]

Yep, there is a special template for Inspector bugs that includes all relevant people into CC list.

        Web Inspector: Fix heap snapshots loading. Loading is now
        conducted by the Profiles panel which prevents accidental
        simultaneous attempts to load the same profile several times in
        parallel.
