[BUG] Waiting for filechooser crashes the page

[israelKusayev]

Context:

• Playwright Version: 1.1.8.1
• Operating System: bitbucket pipelines
• Node.js version: 16.13
• Device: iPhone 13 Pro
• Extra: running tests in parallel inside bitbucket pipelines (Running 26 tests using 4 workers)

Sometimes the page crashes when waiting for filechooser (Happens only on mobile IOS not on chromium)
code

const [fileChooser] = await Promise.all([this.page.waitForEvent('filechooser'), this.page.locator(this.#uploadButton).click()]);
await fileChooser.setFiles(path.resolve('src/images/2mb_sample.png'));

Thank you for the report! Could you run the same with DEBUG=pw:browser* env variable? It'll tell us why WebKit crashes.

Hi I tried running with DEBUG=pw:browser* as for now I can't reproduce the bug, I'll update when I encounter it again

[israelKusayev]

@pavelfeldman I reproduced. the only log I see it

2022-02-09T14:21:44.915Z pw:browser <launching> /ms-playwright/webkit-1596/pw_run.sh --inspector-pipe --headless --no-startup-window
2022-02-09T14:21:44.927Z pw:browser <launched> pid=3932

Your code looks good and the trace looks clean, as in it does not say anything about the crashed page. Is there a chance you could provide a reduced test case that we can try?
