patch 9.1.0223: code duplication in loop to add active text properties
Problem: There are two dense conditions with duplication that needs to
be kept in sync between the while loop break condition and the
condition to skip certain text properties.
Solution: Refactor the loop by moving while loop conditions into the
body of the while loop so they can be shared with skip
conditions. `break` and an `active` variable are used to
handle the outcome of these merged conditions.
