Tests/LibWeb: Fix file path for crash test script src Simply meaning the test would never get the internals object. 2025-02-10 17:09:38 +13:00			`<script src="../../Text/input/include.js"></script>`
LibJS+LibGC: Run FinalizationRegistry cleanup host hook after GC Before this change, it was possible for a second GC to get triggered in the middle of a first GC, due to allocations happening in the FinalizationRegistry cleanup host hook. To avoid this causing problems, we add a "post-GC task" mechanism and use that to invoke the host hook once all other GC activity is finished, and we've unset the "collecting garbage" flag. Note that the test included here only fails reliably when running with the -g flag (collect garbage after each allocation). Fixes #3051 2025-01-23 09:59:22 +01:00			`<script>`
