This was the root cause of #1751
Please close that with this.

@msft-Jeyaram I'm confused what issue #1751 is actually describing - if it's describing an issue in NSLayoutManager with:
CTLineRef fitLine = static_cast(CFArrayGetValueAtIndex(CTFrameGetLines(frame.get()), 0));
then that issue still repros, and this was not the root cause (I may have also just opened a dupe at #1779)

@ms-jihua I updated the bug #1751 .
This might not as well be related, but I have seen the crash upon attempting to obtain
static_cast(CFArrayGetValueAtIndex(CTFrameGetLines(frame.get()), 0)); and the frame is empty.

Are you able to repo as per #1751 steps?

@msft-Jeyaram I am not able to repro the #1751 stack. I get #1758 on develop and #1779 after this change.
