Dotted Grace note and Glissando marking issue

There are some wonky issues involving dotted grace notes and I wouldn't be opposed to disallowing them in Musescore completely due to their extreme rarity and lack of use.

The first one involves the dot placement after the grace note - it often collides with the following note head.

The second bug occurs if I attempt to place a glissando marking after the dotted grace note. Now the glissando line points the wrong way! See attached files for examples. This occurs in Musescore 3.0 and 2.3.
