Steps to reproduce:
# Create a project
# Window->UI Toolkit->UI Builder
# Go to the "Controls" window and find "Button"
# Double-click on it
# Verify, that button becomes added 
# Select it
# Verify, that its data become displayed in the "Inspector" window
# Find the "Borders" section in the mentioned window
# Expand it and select "Width" 
# Hover the mouse on any of the items - Top, Right...
# Observe the tooltip text
# Click on the displayed "px" section in each of the lines
# Observe displayed options

Actual result: It tooltip says "Enter a value as pixel, percentage, or initial" so all the mentioned options should be displayed for the selection. But "percentage" is not on the list. Added screenshot in the "Attachments" section.

Expected result: If the mentioned option is not displayed, so word "percentage" should be removed from the tooltip.
