Similar issue with ESC[1d ESC[2J instead of the bold I get in a terminal. Also at the beginning of the output, the rest of the output appears fine with colors and all.
By the way, my tests open a GUI app as a side-effect (it's pico-test running on PICO-8), and the output is only converted once the app is closed. But that may be unrelated (it this bug is fixed but the second remains, I'll open a new ticket).

While app is opened

App is closed, but only tags after the first two are converted
