Describe the issue:

The first time I try to open the kernel selection menu on a new notebook it automatically closes. ~NOTE: This applies to web only~ <--- I see it in Electron too now. Although it's harder to repro, but the e2e tests hit it all the time so I had to do some janky things to make it able for the tests to run

Steps to reproduce the issue:

1. Launch Positron web
2. Create a new notebook - wait for interpreter to finish loading
3. Click the kernel selection menu
4. Verify context menu displays which allows you to interact with kernel - FAIL

Expected or desired behavior:

When the user clicks on a button to open the kernel menu, it should work.

Notes

This is especially problematic for e2e tests because I'm doing stupid things to work around this menu auto-closing to interact with the kernel.
