Text save participants are overwritten for each extension host

Only on Windows I see this test failing and as such have pushed a skip() for just that:

  1) workspace-namespace eol, change via onWillSave:

      AssertionError [ERR_ASSERTION] [ERR_ASSERTION]: The expression evaluated to a falsy value:

  assert.ok(called)

      + expected - actual

      -false
      +true

Actually seeing this on Linux too, I have pushed a change to disable it when running from web.

@bpasero add you for debugging help. This test works on playwright+macOS, in electron, and also when running from within web-selfhost. I see them failing on playwright+windows but the debugging is so limited that I don't know how to drill into it

@jrieken maybe with this sloMo option you could artificially slow down the test run to get a hold of the dev tools within? But I guess simple timeouts in the test would also help already.

Turns out that this is a race between the web worker extension host and the remote one and the text exposes it.
