The Named SQL window goes away when typing to filter what entries I want (4246430)

In the Editor, after selecting Ctrl+N to bring up the list of named sql, when I type in the named sql box to filter down the entries to get to the one I want, once I hit a point where there is only one entry that matches what I have entered so far, the named sql box goes away and only what I have typed to that point shows up in the editor.

WORKAROUND:
1) Hit Ctrl+N to bring up the Named SQL window.
2) Use the arrow keys to find the entry you want.
3) Once you have the Named SQL you want highlighted, click <Enter>.

STATUS:
