Electron app startup is very slow

What Happened?

When running yarn e2e-test, the startup time for the Electron app can be very slow.

I have tried to adjust the timeout on the beforeAll hook to account for that (at e2e-tests/fixtures.ts:46, introducing base.slow() or base.setTimeout() with different values), but even with a 180s timeout, sometimes the timeout gets exceeded:

  1) basic.spec.ts:8:5 › create page and blocks, save to disk ───────────────────────

    "beforeAll" hook timeout of 180000ms exceeded.

       at fixtures.ts:45

      43 | }
      44 |
    > 45 | base.beforeAll(async () => {
         |      ^
      46 |   base.setTimeout(180000)
      47 |   if (electronApp) {
      48 |     return

        at /home/sty/Code/logseq/e2e-tests/fixtures.ts:45:6

I am currently hunting timeouts that are too short for e2e-tests to run correctly on my config, and this one is the one I have increased the most yet. I could theoretically increase it even further, but at this point I feel like it's a waste of time, and that there's probably a cause to be found somewhere in the code. I don't have any clues though.

Use npx cross-env 'DEBUG=pw:browser' CI=true playwright test to debug browser init and check the logs.

This is the output I get on a 10s timeout:

This is with a base.slow() marker (90s timeout):
