fix: emoji autocompletion overwriting preceding element (#3064)

* fix getPrevWorldRange to exclude empty text children

this prevents the range from encroaching on the node of elements like emojis and pings to prevent them from being overwritten

* fix typo of "word" as "world"

* trigger pr checks
