Correct default appender icon transition jump in Safari #15892

As noted in #15868, when hovering over the default appender icon to the left of the text field, Safari renders a tiny position jump:


This is likely because the browser tries to shift the animation from the CPU to the GPU, mid-animation. 馃槙 By providing will-change: opacity (the newer version of the traditional translateZ(0) hack to fix this), we can tell the browser to render the animation using the GPU right from the start, and avoid this issue:


The docs for will-change recommend removing this after the animation happens, but I haven't been able to sort out a way to get that working here.
