Flaky test: previewControllerShouldRenderTheFrame

[ForNeVeR]

Sometimes (only observed on Windows for now), this test fails with the following exception:

Project Project(name=AvaloniaMvvm, containerState=DISPOSE_COMPLETED, componentStore=C:\Users\runneradmin\AppData\Local\Temp\JetTestRider\152357254\previewControllerShouldRenderTheFrame\AvaloniaMvvm) (disposed) already disposed

I've tried to enable Commands tracing scenario, though nothing interesting has been captured in the logs so far, because IntelliJ's CoreCommandProcessor won't log the failed command name in case of the "Project already disposed" exception.

A log improvement has been merged into IntelliJ 2021.3, which will help with further investigation.

I was able to reproduce a similar exception while opening another project in the same window as I had an Avalonia Previewer opened.

It stopped being flaky, I think.
