accessibility/mac/select-element-selection-with-optgroups.html 

Test is a flaky failure according to history on macOS. Failures have been most recently on Debug. Last failure on Release was at r261505. Will setup expectations across macOS. There is no indication of first occurrence as failures reach the limit of history going back as far as limit of results webpage.

can we use the map function in Vector to make this use less code?
