[BUG] Other shortcut keys are invalid due to every key stroke is captured. 由于每次击键都被捕获导致其他快捷键都失效了

[XDcedar]

Describe the bug

I'm using other extensions in Firefox (and Chrome), which have their own shortcut keys (For example Firefox addon Tree Style Tab has shortcut F1). However if I enable Vimium-C, those shortcuts are invalid even if they are not valid mappings in Vimium-C. (Not displayed in Help menu when pressing ?)
That's not the case in Vimium.

我在 Firefox 和 Chrome 中会使用其他扩展，它们有自己的快捷键（例如 Firefox 插件 Tree Style Tab 有快捷键 F1）。但是，如果我启用 Vimium-C，这些快捷键将失效，即使它们不是 Vimium-C 中的有效映射。（按‘?’时，在帮助菜单中没有显示）
Vimium 的情况并非如此。

To Reproduce

Find an extension supporting shortcut keys without Ctrl/Alt/Shift, for example F1 in Tree Style Tab, and Press its shortcut. (Nothing will happen)
找到一个支持不带 Ctrl/Alt/Shift 快捷键的扩展，然后按它的快捷键。（什么也不会发生）
