Edit Docs Unexpected Behaviour

[EltonGohJH]

Unexpected Behaviour: If I have more than 1 tag, if i use edit command, all the tags will be replaced. Eg initial tag ([123], [456]) -> edit t/789. Both [123] and [456] is removed and replaced
with [789]

From the implemetation point of view, it is understandable why edit tag replaces all the existing tags.
But I think you will need to state it clearly in the docs since the behaviour is kinda different from name etc.
