Browse last command output does not show anything when triggered from TMUX

Describe the bug

Kitty's <ctrl><shift>g to view the output of the previous command in a pager works in kitty, but when triggered from tmux, the pager pops up but no output is shown.

To Reproduce Steps to reproduce the behavior:

Start tmux
echo 'hello'
Press <ctrl><shift>g
For me, I see the less pager window pop up, but it is not populated with text.

Screenshots If applicable, add screenshots to help explain your problem.
