* fix: Invalidate weak ptrs before window Javascript object is destroyed
* chore: add regression test for #14513
This test is similar to the original gist at https://gist.github.com/bpasero/a02a645e11f4946dcca1331d0299149d -- the key is to open multiple windows and add an `app.on('browser-window-focus') listener that accesses window.id.
* fix: last commit didn't test the right thing.
The test needs to run in the main process to reproduce the
conditions reported in #14513
