Inconsistent method for symbol color fill in 6.99

KiCad Version

When changing fill color for these types of symbols, Right Click Mouse on the border, or fill, of the cyan highlighted areas will lead to being able to change fill, however, to fill the arc segment area (yellow), right click mouse will only work if the border is selected. Cannot change the yellow fill color by RCM anywhere on the yellow fill.

And a question: should the segments of this type of shape be filled individually, or should the entire shape be filled with one action?
