After the recent update, when the prefix is visable, not matter outlined or filled, the moving-up animation of the label will "blink" on clicking the component.

Research direction

Start by reproducing the TextInputLayout label animation with a visible prefix in both outlined and filled styles, then trace the label movement triggered when the component is clicked. Done means the label moves without blinking in both configurations; the payload names no source file or test to run.
