Bug 55824 – Web Inspector: [Chromium] Allow dynamic enabling of detailed heap profiles

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

[Mikhail Naganov]

The current approach that requires editing DevTools.js is inconvenient -- it should be allowed to enable detailed heap profiles from Inspector UI.

The proposal is to introduce a keyboard combo (e.g. "leakz") that enables detailed heap profiles.
The setting isn't stored anywhere. Instead, after loading the first profile from renderer, its type
is determined, and the mode got switched appropriately.

We do not break lines in this way - everything should be on the same line

function names are camelCase in WebKit

Looks good except for Alexander's comment. Also, could you factor out this shortcut handler as a separate method parametrized with the easter egg phrase?

I've factored it out, but left it as ProfilesPanel method. But it's now easy to extract the method to any other common class.
