maxerrorlines does not appear to work via robot.running.model.TestSuite.run

[nickbrust]

I have some code that uses robot.running.TestSuiteBuilder:

        builder = TestSuiteBuilder()
        suite = builder.build("some_suite.robot")
        # run
        suite.run(output="out.xml", loglevel="TRACE", maxerrorlines=None)

yet I am seeing the:
[ Message content over the limit has been removed. ]
in the test-case-level error message.

And setting this to any str value (int throws AttributeError: 'int' object has no attribute 'upper') seems to have no effect on the message length (I've tried maxerrorlines="10", ="999", ="NONE" as well).

loglevel is working.

However, if I use subprocess to build a CLI command using --maxerrorlines NONE or robot.run with maxerrorlines=None, the error message is formatted properly.
