file picker unexpected behavior

OS: Ubuntu 18.10 x86_64
Kernel: 4.18.0-13-generic
DE: GNOME 3.30.1
WM: GNOME Shell

Every time I save a file, if I navigate to a different folder than the one the save dialog appeared with, after I've selected the folder for saving my file, if I just start typing, my keystrokes don't go into the filename field even though that is the only field showing for editing and the file name is highlighted in that field.

What happens instead? A search field magically appears and my keystrokes start going there. In order to actually edit the file name, I'm required to click the mouse in the file name field. And, clicking in the file name field causes the filename to un-highlight, forcing me to press Ctrl+A to re-highlight (now including the file extension).

This can't be by design can it? I'm not supposed to just retrain myself to type the filename first and then navigate to the folder I want to save in, am I?

Even if I was willing to do that, sometimes, I want to click on an existing filename in a folder and then edit it. This requires navigating to that folder first. This is worse. Why? Because if I start typing right after clicking on an existing file it takes 2 clicks to be able to start editing the filename after clicking an existing file.

I believe I should be able to navigate to a folder and as soon as I start typing, be editing the file name (it's the only visible field for editing and it has text highlighted in it like it has the focus). There's no reason for a search field to appear just because I navigated to a folder before beginning to edit a file name.

Also, if I click on an existing file, and that name loads in the file name field, I should be able to immediately start typing to edit. I should not have to click in the file name edit field 2x in order to be able to start editing.

If I want to search instead of editing the file name, I should have to click on a search button or use a keyboard shortcut to do that instead. That would be the sane, expected way of doing things.

Please, please, fix this.
