When editing application.properties, a useful popover is shown that helps to complete a key. When part of the key is an enum, for example, spring.jackson.serialization.*, the popover displays the javadoc for the enum's value. This javadoc is displayed without context so it's not clear that it's Jackson's javadoc that's being displayed.

By contrast, the same popover in IDEA makes it clear that it's Jackson's javadoc that is being shown:

The context is important as it's useful to know where the javadoc is coming from. It's also important as it helps with things like @since information:

I don't think it's clear that the 2.6 is a Jackson version.
