Discussed that we can just remove try/catch to surface if there's any setter error.

Description
window.innerWidthdoesn't actually setinnerWidthon happy-dom'swindowobject #10343I'm somewhere between
happy-dom + innerWidthand allow mutationThe reason why I don't care much on changing this is that mutating
innerWidthand affectingmatchMediaisn't possible in real dom. They aren't completely non-writable either but dom spec has rather odd handling that if you writewindow.innerWidth = ..., then you just read the written value afterwards that is different from window's actualinnerWidth.Please don't delete this checklist! Before submitting the PR, please make sure you do the following:
pnpm-lock.yamlunless you introduce a new test example.Tests
pnpm test:ci.Documentation
pnpm run docscommand.Changesets
