Has Regression Range: --- → yes

this is not happening too frequently but if someone want to investigate this, the screenshots of the failures indicate that browser_rules_color_scheme_simulation.js#117 doesn't actually select the node in the iframe, which makes the test wait indefinitely as the expected rule for the iframe node won't be displayed
