☑️ Resolves

• Fix some topic from daily design review
• Tested with nextcloud-vue@main, so need to release for some upstream changes
• Search box
  • text moves on hover upstream
  • buttons are too far
• List items in conversation list
  • Spacing on the left too much upstream ?
  • Avatar circle is slightly cut off upstream
  • Avatar circle should have transparant bg + same bg on hover
• Create new conversation dialog
  • Use JS autosize for description so it auto resizes upstream
  • lock horizontal resizing
• NewMessage input
  • emoji doesn't have hover feedback
• MessageButtonsBar
  • lift a bit for sticky position
  • if date and buttons are on the same level, buttons dissapear (hover event at date should be disabled)

Making list items huge again seams like design reverting

Do we maybe have overwriting somewhere?

UPD: reduced height a bit, but we still have from upstream
height: 48px (2 lines) + 8*2 px (padding top/bottom) + 4*2px (outline offest compensation)
