Fixing RadioButtonGroup exception in Window (#11181)

* discardStaleCacheEntries is moved to a proper place before updating indexToRowMap and keyToIndexMap maps. In its previous place, it cleared the data that was just put in the maps.
Fixes #11143

* Adding test

* Removing extra annotations

* Updating chrome version to 69 in tests (#11182)

* Updating Chrome version to 69

* Updating screenshots taken in Chrome 69

* Fixing screenshots

* Fixing screenshots

* Adding some wait commands to tests

* Fixing screenshots

* Revert: Fixing screenshots

* More screenshots

* - Adding wait commands to make sure the transitions end before screenshot
- Fixing a screenshot

* Correcting a mistake of using wait instead of sleep

* Fixing more screenshots

* Increasing the height of ContextMenu (Because of limitation of new Chrome 69 in terms of minimum window height, ContextMenu size can't be tested with a small height.)
