Library symbol turns opaque when resized/expanded

Description In dark mode, a library symbol that contains a black-stroked element renders correctly at its original size, but becomes fully opaque (a solid dark block) once the element is resized/expanded.

Steps to reproduce

1. Switch the canvas to dark mode.
2. Add a symbol from the Library that has a black line/stroke as one of its elements.
3. Select the symbol and resize it larger (drag a corner handle to expand it).
4. Observe the element as it grows.

Expected result The symbol stays visible and keeps its stroke/shape while being resized

Actual result On expanding, the element becomes opaque
