Grace note after a note (Nachschlag) before a silence results in confusion when importing from musicxml

The following happens during musicxml import: if a nachschlag (a grace note after a note, like the resolution of a trill) precedes a rest, the named nachschlag is moved during import to precede the following pitched note in the same voice.
The same file imports correctly in other musicxml software (for example, it is converted and rendered correctly by libmusicxm and lilypond).

Attached are two pictures, one with the original file and a second one with the result after import. Notice that the grace note is misplaced only if following happens: nachschlag - rest (one or many) - pitched note. Without the pitched note the nachschlag is imported correctly
