Description:
webgpu/whlsl/ensure-proper-variable-lifetime.html

This is a flaky imageonlyfailure.

The first image failure that I see this on the dashboard was 10/152019 at r251120, but it was not a commit that seemed relevant that would have caused this.

It appears the original test expectations were set to failure instead of imageonlyfailure.  Modifying/correcting text expectation in https://trac.webkit.org/changeset/266564/webkit

I attempted to reproduce the imageonlyfailure using the previously used reproduction steps, but was unable to reproduce using those or other combinations I tried at this time.

The test was expecting a blue square outline with white background and center, and received a white square outline with black background and center.
