[Divider] Fix divider for RTL Locale

When having a language with RTL layout direction, the view coordinate is
flipped in the x direction (x=0 on right edge, not left edge). This
caused miscomputation of the divider line position inside the view host,
because we already considered the locale in split layout direction and
it would be double counted if it is flipped again in the view.

This change ensures that the divider layout is always LTR regardless of
the locale to fix the divider line position.
