On advanced search, hover of date filter causes misaligned UI

[remkonoteboom]

Describe the bug
When a timestamp filter is added to the advanced search, it is rather long (in width). Hovering causes the + / - buttons to appear which messes up the css a bit and causes hidden items to be exposed slightly

To Reproduce
Steps to reproduce the behavior:

1. Go to a table layout
2. Click on "Advanced Search" icon
3. Add in a filter for timestamp
4. Hover over that filter.
