Long strings easily saturate the variable view

I am using the "type" stringifier, but it apparently still returns the full string representation for `str` instances. As a result, any long string easily saturates the variable view, such that you can see nothing but a small chunk of the string, let alone any other variables.

Start by tracing the "type" stringifier used by the variable view and inspect how its output is rendered. Reproduce the issue with a long Python string, then verify that the string is bounded or abbreviated so other variables remain visible.
