Fixed bug where selections would jump across multiple different widgets if they were next to each other
Fixed bug where selections would jump across multiple different widgets if they were next to each other

Summary: This makes the canEditOffset be more accurate, checking if its inside a single entity

Test Plan:
Make two dropdown widgets right next to each other, click around and
observe the cursor not snapping around as if they are one single large entity,
but being able to exist between the two
