            Bug ID: 246117
           Summary: Web Inspector: Inline breakpoint indicators appear for
                    every line after refresh+hitting a breakpoint
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: pangle at apple.com
                CC: inspector-bugzilla-changes at group.apple.com

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.
