Addressables: label chip in the asset Inspector renders as two mismatched parts, its remove button carrying a different fill and shape from the chip itself

Steps to reproduce:

1. Create a new project
2. Install the Localization package via "Window > Package Manager"
3. Open "Edit > Project Settings > Localization" and create the Localization Settings 
4. Click "Add Locale" in the "Available Locales" section
5. Tick any locale and click "Add Locales", saving the asset to Assets
6. Select the generated Locale asset in the Project window
7. Look at the "Locale" chip in the labels row of the Inspector
8. Repeat in both the Dark and Light Editor themes

Actual results: 

The chip does not read as one control. Inside a single capsule:

1. The name part and the remove button have different background fills. The remove button carries its own fill rather than sitting on the chip's, so the capsule reads as two pieces stitched together.
2. The two parts are different shapes. The name part is a rounded capsule; the remove button is a smaller squared block that does not follow the capsule's right-hand curve.
3. The remove glyph itself is not legible at its rendered size. In the Dark theme it reads as a pale blob, in the Light theme as a dark blob. In neither is it recognisable as a close control.

The mismatch is identical in the Dark and Light themes, so it is not theme-specific styling.

Expected results: The label chip renders as one control: the remove button shares the chip's fill and follows its shape, and its glyph is legible at the size it is drawn.
