Brief summary of the bug.

When adding a Flow Node Data Filter for Flow Node Dates, the filter preview contains unnecessary whitespace at the bottom of the preview item.

Steps to reproduce:

• Create a process report
• Add a Flow Node Data Filter for Flow Node Start Dates for Today
• Add a Process Instance Filter for Flow Node Start Dates for Today (for any flow node)
• compare the two filter previews

Actual result:

• The Flow Node Data Filter has more bottom padding than the Process Instance Filter (see screenshot)

Expected result:

• Both filters have the same bottom padding.
