patch 8.2.2236: 'scroll' option can change when setting the statusline
Problem: 'scroll' option can change when setting the statusline or tabline
but the option context is not updated.
Solution: Update the script context when the scroll option is changed as a
side effect. (Christian Brabandt, closes #7533)
