Actual result

• The arrow for the “current data” drop-down is incorrectly positioned when zooming in or resizing the window.

Regression range

• This issue does not seem to be a regression. I have managed to reproduce it with the same repro steps with builds as far back as 21st of August 2017, when the dropdown was implemented.

Additional notes

• This issue also occurs when resizing the window and making it smaller.
• Screen cast attached to illustrate the issue.

• For Ubuntu, the arrow touches the drop-down title.
• For Mac, the arrow overlaps the drop-down title.
