Test: Guaranteed working baseline be2a698ffb for popover positioning

[georgewrmarshall]

Description

This PR tests the guaranteed working baseline to confirm popover positioning works correctly.

Testing from commit be2a698ffb ("release: Bump main version to 13.6.0") which is the commit directly after 13.5.0 was cut from main. This should be a guaranteed working baseline since 13.5.0 CI builds definitively have working popovers.

Expected Result: Popovers should position correctly in GitHub Actions builds.

Purpose:

• Establish a confirmed working baseline for git bisect
• Rule out any environmental factors in current CI setup
• Confirm our understanding that the issue started after 13.5.0

If this works as expected, we can use this as the "good" commit for git bisect between here and current main to find the exact breaking commit.

4. Test popover positioning:
   • Click the account menu (top-right)
   • Click the global menu (hamburger icon)
   • Open network selector
   • Verify popovers anchor correctly to their reference elements

Expected Result: All popovers should position correctly since this is the guaranteed working 13.6.0 baseline.

Screenshots/Recordings

Expected Result

Popovers should correctly anchor to their reference elements in GitHub Actions builds, matching the behavior seen in 13.5.0 builds.

Technical Notes

• Baseline Commit: be2a698ffb - Release bump to 13.6.0 (directly after 13.5.0)
• Known Working: 13.5.0 CI builds have functional popovers
• Next Step: If confirmed working, use for git bisect against main branch
• Issue: ALL popovers float unanchored in current main branch CI builds
