[TO FIX] UI bug: filter window in Board configuration closes by space keydown when i try to filter name by "text contains"

How to reproduce:

  1. Create Board View
  2. Go to “Board configuration”
  3. Set “State” for Columns
  4. Click to background to save settings
  5. Click columns filter icon and select “Name”, “contains” and start to enter column name which contains a space in name.
  6. You can not enter a space in filter by “text contains”!

But i can replace space (" “) to underscore (”_") and filter is working right!
