The LibreOffice "47148" is at
https://bugs.documentfoundation.org/show_bug.cgi?id=47148.  Note there that the
"81378" and "99612" in the "See also" are recent. 

In general, there is consideration that the lifecycle management of images and
their caching in an opened document is not handled properly and the way it is
hacked together is not taking advantage of the UNO RTL technology for
accomplishing such control.  Remedy for this needs to be extended to cases
where still-live material is spilled to disk.  That introduces interaction with
auto-recovery, dealing with shut-down cases, etc., and also cleaning up spilled
files that are no longer part of a managed lifecycle.

Unfortunately, this is all unsurprising.

It is important for those working on AOO QA and the many community members who
contribute on this matter to understand that any code solutions that are
devised for LibreOffice are, even when readily adaptable to AOO, not available
without their contributor's permission to incorporate under a license that is
acceptable for Apache project source code.  (The reverse direction does work.)

Please do not quote code and substantial analysis of others in examining bug
reports and repositories elsewhere for confirmation of common problems and the
availability of analysis.
