Description

The queue UI test fails has a couple of flaky points.

Sometimes we see the console errors for network unresponsive -- when this happens the test fails.
When we don't see the console errors for network unresponsive the test passes. The problem is that in the tests we were ignoring the PollingBlock errors, but more errors appear when the network is down, making the test fail when they appear in the console.

There are more sources of flakiness, that can also cause this test to fail. Those are described here and fixed in this same PR:

• Performing a subsequent action when the popup is closed, causes the NoSuchWindowError: no such window: target window already closed error. We need to switch back to an existing window, before proceeding with test actions

• Triggering a tx/signature with an unresponsive network (when we kill ganache) takes a significant amount of time to open the popup. Now we wait for the expected number of windows before switching to the popup and we add a big timeout for this case (it's a max value and won't delay the test if it's not needed, like in FF). There's an issue open to fix this on the app level in this ticket.

• Asserting values from elements found by their css/testid can introduce flakiness as the elements could be rendered without having the expected text yet loaded. Now the approach for these validations has been fixed by looking for the exact selector which includes the text

• A lavamoat error appeared once, but this seem unrelated to this specific test and just saw it once so it's left outside the scope of this PR error caught in retry(): JavascriptError: javascript error: LavaMoat - property "name" of globalThis is inaccessible under scuttling mode.
