Noticed that the search box in trunk shrinks a couple of pixels when selected.
This is because in unselected state the text is italic (and wider) and when selected normal. This can be solved by giving a fixed width to the search box, removing the italic (like in Bug 636014) or exchange the flexible spacer with fixed spacer. I'm on XP now and can't test if the last really would solve the problem.
Created attachment 598397 [details] [diff] [review] Give a fixed width With defining the width the box no more jumps when selected. I gave a width of 25em. If needed this width can be adjusted. When more elements are on the toolbar then the search box adapts the width as before. The patch also gives a width to the search box on Address book which has the same problem.
