LinearProgressIndicator stalls Roborazzi @Preview tests

[as6o]

When Roborazzi processes a @Preview (using the Compose Preview support) containing an indeterminate LinearProgressIndicator (during recordRoborazziDebug, verifyRoborazziDebug, etc.) it stalls for a good 4 minutes or more (whereas all other @Preview-based tests are quick). We assume that the delay has to do with the ProgressIndicator animation so we are skipping those @previews using a custom ComposePreviewTester for now. However, is there a strategy for dealing with such tests that contain animations?

Thanks.
One thing I can recommend is adding the DelayedPreview annotation. With this annotation, you can set mainClock.autoAdvance = false and then use mainClock.advanceTimeBy(delay). This should help the test finish quickly.
The information is in Japanese, but you can refer to the code.
