Found by @MMiller_WMF. It seems not reproducible in a browser emulators (tired FF, Chrome, Safari and Sauce labs and Xcode simulators).
Consistently reproducible in iPhone 6s real device (iOS 13.3.1)
- In Homepage Suggested edits filter selection, click to select some filters - the check marks will overlap the labels
- Click on 'Done' and then open the filter selection again - the checkmarks are positioned correctly.
- Make some new filter selection - the check marks will be overlapping again.
Here is a video from a real device - it shows an additional shift in the label attempting and failing to accommodate the check mark.
