在全屏模式下，如果按Esc以退出输入法的弹窗，会直接退出整个全屏模式。 When I typed something, I may press "Esc" to quit the input method popup. In this case, the fullsreen mod should not be cancelled. For example, look at the attached picture, which is taken when I'm inputing something in the fullscreen mode. In this case, when I press "Esc", the expected behaviour is to close the input method popup without closing the fullscreen mode. The bug has existed for long. I'm using the latest Firefox version for Windows 11.
