Liquidsoap keep old playlist with deleted files instead of playing blank

[giflw]

liquidsoap version: 1.1.1

When I use a directory as playlist and delete all files, liquidsoap keep playing instead of playing blank.

pls = playlist(mode="normal", reload=1, reload_mode="rounds",  "/tmp/music")
out(pls)
