Bug

When switching to a workspace containing Festival in i3 using a shortcut such as Super+Key, the "Key" is written to the search. For example Super+0 writes 0 to the search bar.

Steps

Steps to reproduce the behavior:

1. Open Festival in i3 WM and leave it as the only window in a workspace.
2. Go to another workspace.
3. Go back to the workspace where Festival is using a shortcut such as Super+9.

Perhaps it has to do with synthetic keypresses in Winit. Similar issue in Alacritty: alacritty/alacritty@fa06178

EDIT: After some testing it seems quite literally discarding KeyboardEvents that are synthetic solve this problem. I'll open a PR. Modified the egui-winit crate though.
