Permission/interactivity issue while loading and overwriting editor

[sosnik]

In non-legacy mode, when you try to load a data file while there is text in the editor, you will be prompted to confirm the overwrite.

At first instance, after clicking 'confirm', the command will actually error out because the File System Access API requires interactivity.

Short-term solution

Try clicking Choose File a second time. It will magically work, even with the overwrite confirmation prompt.

Proper solution

Read the docs and fix it.
