STR:

  • Create an empty google spreadsheet
  • Click the A column header to select the whole column
  • Add some data validation (like "List of items", "1, 2, 3")
  • Cmd-click the first selected rows to deselect them

AR: Severe hangs for each click

Ted, looking at the profile Harald provided, do think this is something that could be actionable by the JavaScript team?
