[2.0.20] Autosaving while using Factiorpedia shortcut toggles ALT mode

[oscuro86]

When an autosave pops up, it causes ALT-mode to be toggled when using the Factiorpedia shortcut (alt+left click)

1. Press and hold alt
2. Left click an entity
3. Factoriopedia entry opens as expected
4. Autosave happens to occur now
5. Release alt while the autosave progress bar is showing
6. ALT-mode gets toggled

I do not expect ALT-mode to toggle here, since ALT-mode does not toggle if the autosave hadn't occurred.

This is on Windows
