Steps to reproduce

Havent really found a deterministric way to reproduce it

Expected behavior

Terminal is working and not printing these events

Actual behavior

The PR #5319 didn't seem to have fixed it only what was in following issue #4776 or a regression happened. The terminal is showing raw ANSI escape sequences or mouse / keyboard events and wont let any other interaction with the shell happen.
The general format is:
ESC [ < Cb ; Cx ; Cy M

or escaped:

\x1b[<Cb;Cx;CyM

@Sy-D , did you by any chance run a mouse tracking TUI in the integrated terminal?
