Spark: Textarea rows do not display on separate lines

v12.0.8

Textarea field is not expanding to proper size or showing the return characters in a table or form in readmode. When you edit it in the form, the rows are shown correctly. However, modifying the textarea throws a lightning error:

[Cannot read property ‘getAttribute’ of null]
