There is no file with ID 1. The file list may have changed

[sharpist]

BlazorInputFile throws an exception "There is no file with ID 1. The file list may have changed".

On re-add new files, all previously created objects belonging to previous files aren't saved. Meantime, the index starts with unsaved objects that no longer exist.
Note that saving files at each selection step gives an correct index.

The Chrome inside debugger indicates a problem in inputfile.js
