Repro steps:

• open index.html (example)
• set marginTop to 20

Another repro:

• open index.html (example)
• set lineHeight to 29
• set marginTop to 22

Expected result: No missing row

Actual result: The second row is missing (the one which's bottom line matches the right corner of the poly)

Additional information: Tested method 2 and it works well

Another repro is to set marginTop to 0 (zero). In this case the 10th row (the one which's bottom line matches the left corner of the poly) is missing. In this case both methods fail to show it properly, however in method 2 a short reverse line is shown
