LinearInputControl rendered differently on watch and canvas app

[chienhsiang-hung]

I followed the https://learn.microsoft.com/en-us/power-apps/developer/component-framework/implementing-controls-using-typescript?tabs=after#adding-style-to-the-code-component step-by-step carefully.

When I run npm start watch it rendered successfully as shown.

But when I imported it into my canvas app it seemed to miss the dragable bar and some properties.

seems the watch env is different with the dev env @@
