1544713 - Long running audit blocks other DevTools panels

Status: VERIFIED FIXED

(DevTools :: Accessibility Tools, defect, P1)

Description

[Martin Balfanz [:mbalfanz]]

STR:

• visit https://news.ycombinator.com/
• run the audit
• try to switch to a DevTools panel that you haven't visited before

AR:

• other panels remain blank until audit is finished in the background

ER:

• other panels should not be blocked by audit

I think we need to do one of two things:

• have a fully async audit that can be executed in the background (maybe with a nice indicator in the top-level tab when it's finished), without blocking other panels
• cancel the audit as soon as the developer navigates to a different tool

I would prefer option 1 :)

Verified - fixed on latest Nightly 68.0a1 (2019-05-01) (64-bit) on Windows 10, Ubuntu 16.04 and MacOS 10.13.
The other DevTool panels will be loaded while the full page audit is on-going.

Please note that there might be a slight 1 second hang of the DevTool panel UI right when the audit is finished.
