<edit> "Are a constant text failure on macOS ToT and since 268554@main(dashboard viewable history)." would be better said as "Are a constant text failure on macOS ToT and since Sonoma bring up."

These tests are failing for Sonoma WK1.

Sonoma WK1
REGRESSION (Sonoma23B74+)
Sonoma23A344 -> Sonoma23B7+
- The rebaseline (269479@main) caused the test to consistently pass until the bots updated SDK.

Removing test expectation and rebaseline.
