EAT 0.9.4's parser has no CSI t clause and drops the queries, so images never render. I added a :before advice on eat--t-handle-output that scans the raw output and answers through the terminal's own input function (eat--t-with-env binds eat--t-term). I verified it live: images render and survive window switches, scrolling, and resizing. I guarded the advice-add so it installs only while EAT itself can't answer. Two answerers give tmux a double reply, and it forwards the second one's raw bytes into the pane as keystrokes. The guard keys on eat--t-send-window-size-report, the function an upstream clause would define. I kept an upstream-shaped parser-clause patch locally for a PR to akib/emacs-eat.
