There is an issue when the request url contains many parameters (eg. filter form values) - the url overflows the container.
My proposed solution would be to use ellipsis on it, and on mouseover display the complete url.
Tested it on IE9, Chromium 37 and Firefox 32.

Here is a preview of how it looks:
