100%. What ppl often mixup is shell responsibility and the terminal itself. They are not really to blame for that, because their interactive terminal usage is mostly at a shell prompt.

Idk how they implemented things here, prolly by sidechanneling information to/from the terminal widget. Which is bad, they'd better use in-band terminal sequences for that, so the ecosystem of TEs and cmdline apps can eval the sequences and incorparate them, where they are useful (like the prompt marking OSC sequences...)
