Recover lost spanners if possible

[mercuree]

Now in Musescore 4.2.1 and 4.3.0 (4.4.0 doesn't affected by this issue) if you create spanner (pedal line in this case) and copy/paste it like this, spanner is lost on reopening:

pedal_lost.mp4

But starting point is still there in file:

          <Spanner type="Pedal">
            <Pedal>
              <endHookType>2</endHookType>
              <beginHookType>2</beginHookType>
              <eid>322122547296</eid>
              </Pedal>
            <next>
              <location>
                <measures>1</measures>
                <fractions>1/8</fractions>
                </location>
              </next>
            </Spanner>

Musescore 4.4.0 will also not display it and will delete it when saving.
Is it possible to recover spanner using that starting point?
Real score example where some pedal lines (staff 4, measures 7, 52, 56, 71, 78, 79, 84) are missing, but present in file until resaving.

I'm not sure that this will be fixed, so I'm not creating a new issue.
