Fix E2ETest.ServerExecutionTests.CircuitTests.ComponentLifecycleMethodThrowsExceptionTerminatesTheCircuit

Blazor's error UI was overlaying the button that the test was trying to click. This PR fixes the issue by scrolling the button into view before attempting to click it.

Marks #57551 as test-fixed.

Nice. Do we know why it only recently started failing? And what other branches this might affect?

I think we'll want to backport this and/or #57606 to at least release/9.0. I saw this cause failures in #57560.

Nice! If this is a reliable fix, you could probably unquarantine the tests at the same time (since they were not actually flaky but 100% failing all the time).

I'm not totally sure, but it seems related to the testing environment. The way I was able to repro this was shrinking the browser window vertically. I tried various Chrome versions to see if it that was the cause, but it didn't make a difference.

Hm, let's wait before merging. Despite this fixing the problem for me locally, it didn't seem to fix the problem in CI...

@MackinnonBuck merge or close?

[MackinnonBuck]

Let's close for now. I'll open a new PR when I revisit the test failure.
