Python library "linuxcnc" has error

Who can find in source code one error.
I use linuxcnc.org/docs/2.6/html/common/python-interface.html
and if I use c.mdi (command). It doesn't rotate axis
If I use with cos or sin - working correct.
But if I send only "g1 X100 f10000" - move without "cos or sin"
If I use interface line mdi or telnet - all working correct

I see you are using master so you might want to use this:

linuxcnc.org/docs/devel/html/config/python-interface.html

I haven't checked but maybe something has changed.

I just pasted not the last link.
It does not matter.
The mdi command in this library works the same.
If you rotate axis by "g10 l2 p1 r-30" - this will not work correctly.
