Also needed to modify the delay for stability. Initially, I removed `setAutoDelay` since this has caused issues previously, but this caused a failure in linux (when previously linux has never failed). However, keeping the auto delay and adding additional small delays seems to be stable with all of the other changes to the test. The test passes in CI with multiple runs of 100 on all OS's with the proposed changes.

Can we move this block to l72 right after we get pointToClick...since button is already initialised by now..
It might bring some instability while we are in the midst of drag to do this block and then probably we can remove this additional delay when we have autoDelay
