Saving a project to a windows shared drive and loading it again doesn't restore Jmol views

Following https://www-test.jalview.org/tutorial/exercises/ex-4-Saving/ - if the example project is saved to a network drive and loaded again, the Jmol window shows an error message saying 'couldn't load C\:...\AppData\...'.

This sounds like JAL-2275 (which has not been fixed :( ) but also like other issues to do with the filename fixing logic used to insert the latest temporary file containing the structure data when restoring Jmol saved state.
