Documentation search results are missing context

[mdickinson]

For the Traits 6.4 docs (https://docs.enthought.com/traits/6.4/), the documentation search results include context. For Traits 7.0, the search results do not contain the expected context. It looks as though something's going wrong with the JavaScript somewhere. This may be a bug in the ETS Sphinx theme (mostly likely an incompatibility between that theme and more recent Sphinx changes).

Screenshots: 6.4 (https://docs.enthought.com/traits/6.4/search.html?q=HasRequiredTraits)

7.0 (https://docs.enthought.com/traits/search.html?q=HasRequiredTraits)
