The notes aren't displayed in Firefox nor Chrome.

it seems like a Safari bug.

Summary|SVG image with notes not |SVG: Support for missing

--- Comment #5 from eisa01 <***@gmail.com> ---
It's not a Safari bug, the Safari rendering is correct.

I had a look at the SVG code.

It uses the "Maestro" font which is not installed on my system. As such it
defines missing font glyphs to be used instead. This was part of the SVG
standard but has been deprecated removed from SVG 2.0, and support has been
removed from Firefox and Chrome.

It's still valid SVG in the 1.1 version, so it's an open question whether
LibreOffice should support it. I would say the standard for LibreOffice could
be different than web browsers that try to be on the leading edge and rather
implement web fonts.

"When SVG was specified, support for web fonts was not widespread in browsers.
Since accessing the correct font file is however crucial for rendering text
correctly, a font description technology was added to SVG to provide this
ability. It was not meant for compatibility with other formats like PostScript
or OTF, but rather as a simple means of embedding glyph information into SVG
when rendered."

The SVG was created by MakeMusic 2014b.v4722, so you can encounter files with
this in the wild.

Dear eisa01,
The svg fiter was replaced by another one.
Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.

Still present

This should probably be classified as an enhancement
