Expected Behavior 🤔

When clicking the padding-area, the cursor jumps to the nearest position like it does for single-line textfields

Notice that the top & bottom is the same (we can't change it), it's not perfect but it's already an improvement.

I think that if we decide to spend time on this, we might as well explore #22544 (comment).
