Editor redraws continuously after running scene with F5 / F6

Issue description

The editor redraws continuously after running a scene with F5 / F6, but this does not happen when running a scene with the buttons in the upper right of the editor. Redrawing does not stop until the editor is closed. This can cause the system to run hot and drain battery quickly.

Steps to reproduce

Enable update spinner if not enabled in editor settings.
Press F5 or F6 to run a scene.
Notice the spinner going even after the scene is closed.

Can you point the exact commit you compiled? Which rendering backend are you using in the project? Can you reproduce this in a brand new project, or only in a specific project? If you can only reproduce this in a specific project, please upload a minimal reproduction project to make this easier to troubleshoot.

Also, can you reproduce this in any of the 4.0 betas to determine when the regression started?

Just rebuilt again with d93b66a, bug is present.
Bug is present in beta 13, but not beta 12, 9, or 6.

This is with the Vulkan forward+ renderer.

This is reproduceable in a new project with an empty 3d scene.

Bisected to dd3a1b0 (pull request #71328) and confirmed the issue is fixed by a revert of that commit.
