A recent patch had been merged into the Blue Ocean code that resolves an issue we've been tracking:
We should probably upgrade Blue Ocean when this patch makes it into a released version.
BlueOcean 1.3.0 installed on Prod. Barak, could you please confirm if the bug is fixed and we can close this ticket?
It turns out the bugfix did not make it to 1.3.0 as can be seen in the discussion on the Jenkins ticket. So this ticket will need to wait for 1.3.1
BlueOcean updated to 1.3.2 so hopefully this time it's fixed.
