[Bug] Prism editor text selecton is broken when autocomplete is open

[ewanhowell5195]

if the autocomplete is open in a prism editor (cem template loader animation editor) and you hold left shift to select text, then spam left arrow (not hold), it selects one character, then unselects, then selects the next character, then unselects. The intended behaviour is that it selects all the text.

to add on to this:

selections in general do not respect the cursor location when the autocomplete is open. if you highlight some text starting from the right and finish on the left, the cursor should be on the left of the selection. if you then hold shift and arrow key right, you would expect the selection to get smaller, shrinking from the left side. instead the cursor is on the right of the selection and makes the selection larger
