When the Kile window is smaller than needed for the "find" menu, the window resizes itself to fit the new menu as soon as focus is lost on the window.  This is a problem because if the user has set the window size to something they like, everytime they use "find", they will have to reset their window size.  For example:

I use half of my screen (resolution: 1366x768) for the editor, and the other half to view the output (usually a dvi or pdf).  Every time I hit "CRTL+f" and then click on the output, which happens every few minutes, my editor window resizes and overlaps with the output part.  This is exremely annoying.

An easy partial fix might be to just shrink "find" menu's minimum requred space.  Currently, part of the menu is just blank, and is not necessary.

Reproducible: Always

Steps to Reproduce:
1. Open an editor window in Kile, and shrink it to be horizontally small (e.g. a few cm).
2. Hit CTRL+F
3. Click outside of Kile on another window (such as a pdf)
Actual Results:  
The window will now be resized to fit the "find" menu."  It also cannot be resized to be small again until the "find" menu is closed.

Expected Results:  
The window should not resize, and should remain with the size it was given in the first place.  The "find" menu should stay collapsed, as it is when you first hit "CTRL+F"

This has happened with several versions of KDE (and KDE running under Gnome and Unity).
