Description

I have seen similar issues raised but they were all solved by something else yet this issue is still present on chrome browser:

!screenshot_20190703_104702

The integration is: Database (select * from contact) -> mapper -> Todo connection (create task)

Todo connection was taken from here and created via customizations -> upload swagger specification.

This issue is blocking some of QE automated tests.
