Fix "Keep selection when right-click outside of selection" not work issue

Browse Source 
Make right-click message handler x-margin calculation right.
Previously, the incorrectly used unsigned variable (size_t) overflowed with negative numbers due to incorrect calculation of margin size.x (where possible horizontal scrolling was not taken into account...).

Fix #16325, close #16332
