[lint] Multiple linters with unique function objects in configs fail to merge #1622
Description
Describe the issue
When multiple linters are configured, each with its own configuration, codemirror fails to load when the following lintConfig keys are set to unique functions: markerFilter, tooltipFilter, and hideOn.
I believe the issue is caused by the following lines due to how the function objects are compared by default.
