Polish: Break long descriptions better when looking at single incident

[hmpf]

Currently, after clicking on an incident, if the description is very long it is truncated. By clicking the description the entire description is shown over as many lines as is necessary, but the close-button moves downwards to sit in the middle of its box. For me, this leads to an annoying flash as the box-size changes and the icon moves.

IMO it would be better if either the entire description is always visible (so that the close button never has to move, or otherwise that the close button never moves regardless of how many lines the description needs.

The description that triggered this was 190 characters long, the browser window was 1390 pixels wide.
