remote bash hotkey CTRL + L overrided

In a serial terminal or running some background task that keep printing text, it will make screen messy when I using text editor like vim. e.g.

Generally, a terminal app like tera-term/putty/mobaxterm will pass the keyboard event CTRL + L to the remote and the screen will be cleared and recover the editing text, just like:

But the now v2.7 version of WindTerm will just clear the whole screen and keep 1 line, it makes the serial terminal editing or some type of debuging unavailable. Please kindly give a help fix it, or is there any opinion disable is(CTRL + L hotkey)?

Reproduce the issue in a serial terminal while Vim or another editor is active and background output is printing, then trace how WindTerm handles CTRL+L. Compare the current screen-clearing behavior with the described remote-terminal behavior; done means CTRL+L reaches the remote shell or editor and the editing screen is restored.
