Provide a general summary of your changes in the Title above

Pull requests without a rationale and clear improvement may be closed
immediately.

Please provide clear motivation for your patch and explain how it improves
Dash Core user experience or Dash Core developer experience
significantly:

• Any test improvements or new tests that improve coverage are always welcome.
• All other changes should have accompanying unit tests (see src/test/) or
  functional tests (see test/). Contributors should note which tests cover
  modified code. If no tests exist for a region of modified code, new tests
  should accompany the change.
• Bug fixes are most welcome when they come with steps to reproduce or an
  explanation of the potential issue as well as reasoning for the way the bug
  was fixed.
• Features are welcome, but might be rejected due to design or scope issues.
  If a feature is based on a lot of dependencies, contributors should first
  consider building the system outside of Dash Core, if possible.
