Summary0002365: Assertion is thrown when backspace key is pressed after a long text is entered
Description

Happens with 100% probability.
Didn't immediately crash application in Release mode, but probably causes unintended memory access.

Steps To Reproduce
  1. Run "Application Tutorial" (demo application included in Noesis package) in DEBUG mode
  2. Enter a long text (30 characters seem to sufficient, but the longer may be the better)
  3. Press Backspace key
    // Assertion is thrown -> see the attached image

I am unable to reproduce this. Could you please, paste the exact text you are using? And if possible, the values of the vector mRuns from the function that is crashing HitTestTextPosition.

Thank you

For example, I can reproduce it with text "123456789012345678901234567890" (30 characters).

Inside HitTestTextPosition, mGlyphs is a vector with size 29, but is indexed with idx=textPosition+1=29, which is beyond the range of mGlyphs.

mRuns is 1 element vector, please find its contents in the attached screen capture.

Thanks.
