Description

Typing a for loop end up in infinite loop due to auto refresh at - for (i=0; i<5; ) I think because there is no i++ it cause an infinite loop.

Research direction
Investigate the auto refresh logic in the PUG preprocessing module. The issue is that a for loop without increment (e.g., ` for (i=0; i<5; )`) causes an infinite loop. Look for how the preprocessing triggers re evaluation and add a safety check or proper handling of such loop constructs. The relevant code is likely in the preprocessing or live refresh code.
