Description Karl Dubost 2023-09-04 16:44:18 PDT

1. With STP 177 on a MacBook
2. Open Web Inspector - Timelines (Set to start and stop automatically on page loading)
3. Type about:blank in the URL bar
4. The timeline starts recording and eventually stops after two seconds

Result:
In the overview section (bottom area of the Timeline tool), the first line is about about:blank
There is a spinning wheel during the loading process. This wheel stops for normal pages once the loading has been completed. For about:blank it never stops, like if it didn't receive the right event to make the decision to stop.

I can reproduce this bug in mini browser and STP 177. I am working on a fix.
