Alert box text selection

[emartinez-usgs]

Double-clicking the first word in an alert box <p class="alert error"></p> should select the text of the first word, but it does not. This may only happen if there are multiple lines of text in the alert box (untested). This is fairly minor, but may be more important if that first word is a link (untested).

A quick fix was to add pointer-events: none to the pseudo-element for the container. It is not clear if this will fix all concerns.
