[added] Easy method:

• a) Wait 20-30 seconds after opening this page.
• b) Select the “Test Popup” button.
• c) The typewriter effect adds but fails to remove.

Yes, it happens regardless the selected initiation option (upon page load or when visible).

To test the effect as used:

• 1) select the “Test Popup” button,
• 2) watch the typewriter effect begin (delays a few seconds),
• 3) select outside the popup,
• 4) wait for some duration: 5-10 seconds but longer adds more,
• 5) select  the “Test Popup” button.

Wait the 20-30 seconds , select the “Test Popup” button, and the typewriter function shows no extended wrapping. 👏👏👏
