I've been using multi-account containers for a long time. I've always used 'ctrl + shift + # of container' to open new tabs in a specific container. Recently, that feature has stopped working - but only for some containers? I can still open containers 1 and 2 using that shortcut, but my other containers just don't respond.

I've tried deleting the unresponsive containers and creating new ones, but that doesn't fix the problem. They work great otherwise - I can still open them with my mouse. Is there a fix for this?
