Exporting SVG - differs between CLI and GUI

Issue type

Import/export issue

Bug description

When exporting to SVG, the result is sligtly different between using CLI "mscore -o output.svg input.mscz" and the Export/SVG dialog in the GUI. When opening the CLI-SVG in Inkscape and selecting all (CTRL-A) not only the printed area is selected but the whole page including blank areas. When doing the same with the GUI-generated SVG, only the musical output is selected. With the GUI-SVG file, I can simply press CTRL-SHIFT-G to "crop" (set page-size to selection) to selection. With the CLI-SVG file, I need to delete that empty background-like object, to be able to reduce the page-size.

The only difference in exported SVG files is an additional line after the <desc> in CLI-SVG file, which gets converted to object "path1" once opened and saved with Inkscape. Example:

<path class="" fill="#ffffff" fill-rule="evenodd" d="M0,0 L1672.44,0 L1672.44,4251.96 L0,4251.96 L0,0 "/>

Steps to reproduce

1. mscore -o output-cli.svg input.mscz
2. Export/SVG dialog in the GUI, save as output-gui.svg
3. compare files

Start with the CLI SVG export command and the GUI Export/SVG dialog, then compare their generated SVG files as described. Reproduce with MuseScore 4.1.1 and inspect the extra page-sized path after the element. Done means both export paths produce equivalent SVG selection bounds without the unwanted blank background object.
