ID 351968 - str(nuke.root().frameRange()) fails to return a custom root frame range

Problem summary
str(nuke.root().frameRange()) fails to return a custom root frame range.

Customer reported version
nuke.11.1v2

Customer reported platform
centos7

Steps to reproduce

1) In a new Nuke script, open the Project Settings ('S' key when the cursor is over the Node Graph).

2) Change the root frame range to any custom length.

3) Open the Script Editor by right-clicking on any pane > Windows > Script Editor.

4) Select the Viewer node. Enter and run the following command: 

str(nuke.root().frameRange())

Regardless of the values you set for the root frame range, this command will always return:

# Result: '1-100'

Workaround
You get the correct root frame range if you access the Viewer knob directly using the following command:
nuke.root()['last_frame'].value()
