Attached file Testcase #1

STEPS TO REPRODUCE

  1. load the attached testcase
  2. Shift-Reload
  3. goto 2

ACTUAL RESULTS
At 1. the flex container (teal border) content-box height is ~9px. After reloading it a few times it becomes ~94px. When it's the larger size, opening the devtools window and clicking on the flex container makes it snap back to the smaller size.

EXPECTED RESULTS
Every load should produce the same layout. I think the larger size is probably the correct one. Chrome renders it with the larger size, fwiw.
