Linux / Editor with doubles and GCC sanitizers

### Issue description

The `Linux / Editor with doubles and GCC sanitizers` build can fail with a `attempting free on address which was not malloc()-ed` crash in the `Open and close editor (Vulkan)` step.

https://github.com/godotengine/godot/actions/runs/5366302204/jobs/9735786296#step:15:138

The failure doesn't seem related to either PR (in fact one of them is just a docs change). I have only seen this issue these two times, still probably worth looking into.

### Steps to reproduce

Open and close https://github.com/godotengine/regression-test-project/archive/4.0.zip using the Vulkan renderer.
