Flipping direction arrow should have a larger selection area

When using commands flipping direction arrow comes up, and if highlighted and clicked the direction of crvs can be flipped.

I feel the highlight to turn the arrow black(getting the flip arrow to appear) doesn’t happen sometimes.
The selection area, hot spot?, should be a little larger than or arrow thickness a bit more.

Below is what should show, but even with mouse cursor on the arrow, doesn’t show the flipped arrow.
