That is expected.  If you want to count screen lines, try setting
display-line-numbers to the value 'visual'.  However, that will
display numbers relative to the current line, so maybe this is not
what you want.

This is also expected.

No, these properties only affect the display, not how Emacs counts
lines or moves point: those are still done on the actual buffer text.
