Description

This shows up intermittently in our test suite: ios.macos.Titanium.Blob.image dimensions should be reported in pixels (10.15.7) *Error Message* expected 6 to be 11 *Stacktrace*

Some other tests confirm the issue (i.e. the systemredcolor test should always be 6x6 in 1x, 12x12 in 2x density, but we sometimes see it say it's 12x12@1x - so it's reporting a density of 1x but is actually 2x).
