JetBrains: Make the search box dropdown multiline

Created by: vdavid

Context

The web view is a large webview by default. Many items in the dropdown should fit in it.

Problem

The dropdown is often (but not always!) rendered as a single-line thing.

It looks like this: (But there are several items in it, and it scrolls!)

Solution

Not sure why this happens. Figure out the cause and make it always use the space it has.
