## Summary
<!-- Please brief explanation of the changes made -->
Add `try catch` block to mute the error when `smoothCornerScript` is
called twice.

## Details
<!-- Please elaborate description of the changes -->
According to the [MDN documentation on
`registerPaint()`](https://developer.mozilla.org/en-US/docs/Web/API/PaintWorkletGlobalScope/registerPaint#exceptions),
this function only throws two errors. One when the parameters aren't
met, throwing `TypeError` and the other when a worklet already exists
with the given name, throwing `DOMException`. I thought that any of
those two case won't happen in this particular case, so I just no-oped
the `catch` statement. If it is not a good approach, I can narrow the
error down to the later one, `DOMException`.

### Breaking change? (Yes/No)
<!-- If Yes, please describe the impact and migration path for users -->
No.
