Rapid resizing while typing in prompt-buffer (`M-l `or `Ctrl-l`)

[logoraz]

Describe the bug The prompt buffer was simplified for 4.0.0-pre-release-9, and part of this simplification removed some padding that kept the count field "static", now it changes when typing a url search (via M-l or Ctrl-l), this creates an undesired rapid resizing "flicker" effect.

Images to show current suggestions and mark count feature pre-release-9 (that resizes rapidly while typing search):

Image of pre-release-8 where there was padding (does not exhibit resizing):

Steps to reproduce the issue Execute M-l or Ctrl-l and start typing, then you'll notice the field on the left displaying Open URL [ #/##] will change in size as one types a url. Previously, there appeared to be a padding provided to prevent this.
