Bug 246117

Summary: Web Inspector: Inline breakpoint indicators appear for every line after refresh+hitting a breakpoint
Product: WebKit Reporter: Patrick Angle <pangle>
Component: Web InspectorAssignee: Devin Rousso <hi>

Description Patrick Angle 2022-10-05 15:17:03 PDT
Steps to reproduce:
1. Go to apple.com/iphone14
2. Open Web Inspector
3. In the sources tab, add a breakpoint on line 9336 of main.built.js (the line contains `let e = new DOMMatrix(t.getPropertyValue("transform")),`)
4. Refresh the page.
5. The breakpoint will hit, but it will take minutes for the resource to appear (it'll just be a frozen spinner for awhile).
5. Once the resource appears, notice that every single line has an inline breakpoint indicator, but they shouldn't.

Notes:
I suspect that the long wait is us trying to add all these indicators to the DOM alongside the pretty-printed source.
