[bug] Values like fill, rel, and hug are applied to min/max width/height but UI still shows “fixed”

[spartan-uyen]

Summary:
When selecting values like fill, rel, or hug for min-width or max-width, the value is correctly applied to the element. However, the UI still displays “fixed” as the selected option, which is misleading and does not reflect the actual applied value.

Steps to reproduce:

1. Open the width settings of an element.
2. Set the min-width or max-width to fill, rel, or hug.
3. Click outside to apply the value.

Actual result:
The value (e.g., fill) is applied to the element's layout, but the dropdown or selected label still shows “fixed”.

Expected result:
The dropdown or selected label should update to reflect the actual applied value (fill, rel, or hug) instead of remaining on “fixed”.
