sql developer filter entry bug

Here's a bug with the filter entry field in sql developer. 1. enter a filter which gets saved. In this case, owner='joshm' 2. now clear the filter field. 3. type 'o'. "owner='joshm'" pops up as a completion. the typed 'o' is highlighted. 5. type another character, for example 'x'. the 'o' is erased because it is highlighted. 6. once in this mode it becomes nearly impossible to type, since each character erases the previous.
