TailwindCSS doesn't work with onMount

[karchung0930]

I'm not sure if this is bug related to Svelte or TailwindCSS, whenever I put this inside the onMount:
listClass = `h-[50px]`;
It works, but not when it's with template literal:
listClass = `h-[${listHeight}px]`;
What I mean by not working is that I can see the class is applied with h-[50px] but no CSS is being generated for this like height: 50px;.
Is this a bug with onMount?
