Preventing long strings from overflowing (fix #5934)

[ffranchina]

Fixed the bug for which the text was overflowing if it was containing a single very long string (see #5934).

Description

The fix makes use of the word-break CSS property and its recent option break-word and supports the option break-all as a fallback solution on older browsers.

Motivation and Context

Fixes #5934.

How Has This Been Tested?

Tested on Firefox and Chromium on Linux and Edge on windows.
