JetBrains: Tooltip for showing overflowing text itself overflows

Created by: philipp-spiess

This happens because the words are not broken mid-word so long words (e.g. filenames in our path) might cause it to overflow the tooltip container.

You can see this happening in action in the video I posted here: https://github.com/sourcegraph/sourcegraph/pull/36809. Link to video (see it overflow at 4:11)
