[MusicXML import] alignment and offset of texts in vertical frames not preserved

Import attached MusicXML file. Save in MuseScore format. Open MuseScore file.
Result: non-standard alignment and offset of texts in the title frame have been lost.

Notes:
- this issue does not affect a MusicXML file containing only title, subtitle, composer and lyricist in their default positions.
- in MuseScore 3.4.x, styles applied to title, subtitle, composer and lyricist enforce their default positions.
- in MuseScore 3.5.0, no styles are applied to title, subtitle, composer and lyricist, after saving / loading to / from MuseScore format, they all end up in the upper left corner of the title frame
