Layout not registering number inputs correctly after undoing

[wiskill]

Layout not registering number inputs correctly after undoing a connected line (poly line).

Reproduction:

1. Draw a line
2. Type 10, Enter
3. Draw a second line with out inputting numbers (either by reference or whatever)
4. Undo the line (Ctrl+Z) (Still continuing drawing line and not cancelling draw tool)
5. Draw second line again
6. Type 10, Enter
   7)You will get a line with a random length instead <--- BUG

This has been bothering me since Sketchup 2014 and prior, it would be nice if it was finally fixed.
