Keyboard input does not follow focus when using XEmbed applications

Welcome

• Yes, I'm using the latest major release or the current development version. These are the only supported versions.
• Yes, I've searched similar issues and discussions on GitHub and didn't find any.

Current Behavior

When using XEmbed applications, occasionally keyboard input does not follow focus. When I focus away from the Xembed app to another, the I3 UI shows the focus has moved, but all keyboard input remains on the Xembed application.

Specifically, I am running tabbed alacritty --embed (https://tools.suckless.org/tabbed/, https://alacritty.org/)

Expected Behavior

Keyboard input goes to the focused window.

Reproduction Instructions

I have been doing:

tabbed alacritty --embed, then Ctrl+Shift+Enter in there a few times to open some tabs. Trigger i3 keyboard shortcut for focus Left and focus Right to focus/unfocus it. Type some letters in between.

Occasionally -- not always -- the input remains on the tabbed while it should be on the other window. The UI always highlights the correct window (that is, the UI highlights a different window than keyboard input goes to)
