Importing 10+ files mixes up filenames

[danbalogh]

When importing more than ten XML files into a project, the filenames seem to get mixed up. I do not know if this is specific to XML or it happens with other types of documents as well, and I do not know the exact circumstances to reproduce it. It never happened to me when importing my documents for a project in batches of 10 files at a time, but it always (or almost always?) did when I imported a larger number of files (upwards of 20, under 100) at once. None of the individual files were very large (up to 20 kB, most under 10 kB). I have encountered this problem on two separate PCs, both running Windows 10 and using Firefox.
By mixing up, I mean that filename AAA containing the text aaa, filename BBB containing bbb, filename CCC containing ccc and so on become, after import, document name AAA containing the text ccc, document name BBB containing the text AAA, document name CCC containing the text bbb. etc.
