Inline (One-line) JavaDoc comments not rendering at all.
已回答
One line JavaDoc comments placed before Enum element (like in `javax.lang.model.element.Modifier` below) do not get the option to render them. CTRL + ALT + Q on these elements toggles rendering for JavaDoc of the class itself (nor does a javadoc render gutter icon show at the line).

This is a pretty interesting bug, considering IDEA allowing for these types of comments to not be automatically formatted.
Editor → Code Style → Java → JavaDoc → Other → option “Do not wrap one line comments”.
