1537970 - Downloading a blob URL breaks the markup view

Status: RESOLVED DUPLICATE of bug 1347761

(DevTools :: Inspector, defect)

Description

[Greg Tatum [:gregtatum] (REO Fx132)]

Steps to reproduce

• Go to https://profiler.firefox.com/public/c1df573e201c47c9888beb8ad11d71be52b159cf/calltree/?globalTrackOrder=4-0-1-2-3&hiddenGlobalTracks=1-2-3&thread=0&v=3
• Click "Save as file..." in the top right
• Open inspector
• Click "Firefox 2019-02-15 11.06 profile.sps.json.gz (201 kB)"

Expected results

• I can still inspect the page, and the markup view has DOM nodes in it.

Actual results

• The markup view is empty. There are errors in the browser console. I have to close/open devtools for things to work again.
