print/crashtests/reload-crash.html is incorrect

[atjn]

Problem

The test print/crashtests/reload-crash.html is not correct.

The test assumes that after opening a print dialog, JS execution continues. The printing spec requires that JS execution is paused when a dialog is opened.

Firefox and Safari follows the spec and pauses JS execution. Therefore they fail this test with a TIMEOUT.
Chrome and Edge does not follow the spec, therefore they pass this test.

There are also other issues with the test which are detailed here: https://issues.chromium.org/issues/40280568#comment9

Solution

To make the test work properly, you need to cancel the print dialog, which is not possible on WPT. (* maybe I am wrong about this, I am not a WPT expert)

The test is for a very specific Chrome bug, so maybe it should simply be removed from WPT and instead live in the Chromium source as a custom test? At the very least, it should be marked tentative and/or optional to show that there is an issue with it.
