Type-ahead vanishes after a short while

[teo1978]

Steps to reproduce:

1. open a folder in Nautilus
2. start typing the name of an existing file
3. wait for several seconds, or hours for that matter
4. go on typing the name of the same file

Expected:
no matter how much time passes between steps 2 and 4, the type-ahead input box should never go away on its own, it should only go away when you click somewhere else. So, at step 4 you should be able to keep typing the name of the file and it would be selected

Observed:
if at step 3 you wait more that some arbitrary (and pretty short) time threshold, then the very input box in which you were typing on the bottom-right disappears, and whatever you typed is lost. So, at step 4 it is like you statr typing a new filename from scratch, hence losing the selection that had been made, selecting some random file that happens to start with the new characters you are typing, or none if none exists.

I guess this is intended, but it's wrong. As usual, the people maintaining Nautilus have made an idiotic design decision that degrades Nautilus usability instead of improving it.

I'm pretty sure this didn't use to happen. I'm not sure if it is a "new feature", or if it was already there but they have decreased the threshold time. It is also possible that nothing has changed and I hadn't noticed it before, though I doubt it.
