Probably web tests requiring dart:html must be started with flutter test --platform chrome or this?
@miquelbeltran @vbuberen any idea?

[miquelbeltran]

Web tests were not running before either, so we can remove them, skip them, or renaming the file.

Integration tests for chrome are not enabled on the repo yet.

This seems to be good to merge, no?

Added _disabled at the end of the web test, which I don't find optimal, but it works now.

Why didn't these tests ran before (and without an error), as you mentioned?

they were sitting in the web package and there was no CI job running them. I have no idea if they work or not 😬
