Fraction inside root

[DanijelHuis]

Hi,

If you look at the screenshot below, when typing fraction while inside the root, you cannot continue writing anything under that root, it continues to write formula outside of the root. The problem is, I assume, that you cannot somehow select that fraction as you can other elements so it doesn't really know where to continue. Because of this you also cannot delete just the fraction but it deletes the whole root.

Is this a bug or I am missing something?

Fractional nesting also has this problem.
