This is called background-colour-erase (BCE) and is not supported by

Applications should not depend on this behaviour unless the bce flag
capability is in the terminfo description and for TERM=screen it is not:
$ infocmp -x xterm|grep bce
OTbs, am, bce, km, mc5i, mir, msgr, npc, xenl, AX,
$ infocmp -x screen|grep bce
$
