for and while loops not being converted

[shadichy]

while true; do echo 1; done

turns into

REM UNKNOWN: {"type":"While","clause":{"type":"CompoundList","commands":[{"type":"Command","name":{"text":"true","type":"Word"}}]},"do":{"type":"CompoundList","commands":[{"type":"Command","name":{"text":"echo","type":"Word"},"suffix":[{"text":"1","type":"Word"}]}]}}

the same applied to for loop
