Can't delete single row

[YanuszDupa]

When single row is selected , I can't delete such row , only when 2 or more rows are selected then delete button is active.

There is some magic there.
It is necessary to click on the row header and, without releasing the mouse button, move the cursor to the first cell.

Is the way to fix it? Or was it done on purpose?

These are the features of the wxWidgets implementation
