warp cannot using other input languages except English, because CTRL + SPACE is causing pane split on right, but this hot-key is never set to warp
environment: ubuntu 24.04 x64 and fcitx5.
this phenomenon appeared in recent updates, and the language switching key combo is working well in gnome-terminal and terminator, as well as all other ubuntu applications.
