Blocked on #138812

This is blocked because currently we can't support screenshot reports of arbitrary size. The original test ignored the problems with it. This has been skipped for a long time but the work to support the needed functionality is on the roadmap.

I think there are a few measures we can take to make large screenshot testing better:

1. We may choose to delete these tests for now and bring them back once we build better support of capturing large dashboards.
2. Then we only need 1 test for a large PNG, not PDF.
3. The test should be decoupled from the Dashboards app. We can create an example app under SharedUx ownership to verify capturing a large screenshot report.
