On "lens" visualisation I have following problem after upgrade to v8.3.2.

Problem is triggered by Vertical left axis - after removing it everything works ok, so I guess this is Kibana bug.

Hi @cyberzlo thanks for reporting this. I tried to reproduce the issue without any luck - if you happen to still have the broken visualization or are able to turn it into broken state again could you export it and share it here?
