Cockpit terminal page does not capture common keyboard shortcuts

[symexec]

I am using cscope on Cockpit web terminal to browse a source code. The Ctrl+T shortcut used to unwind the tag stack is captured by Chrome/Mozilla, which then opens new tabs. Even if I remap the said shortcut to something common, like Ctrl+K, that too gets captured by the browser. How do I forward the browser keyboard shortcuts Cockpit? I used a few browser plugins that disable the keyboard shortcuts, but then those plugins suppress the shortcut altogether, neither forwarding to the browser, nor to Cockpit. Hence, those are useless.
