Previewed file changed when QTTabBar is used

[Geeyun-JY3]

TLDR: turn off QTTabBar -> Options -> Folder View -> Enhanced incremental search in view

---

Describe the bug
Support QTTabBar

To Reproduce
While QTTabBar installed, unable to peek any file or folder selected. Instead, it will peek another file in the folder (most of time it will peek particular one file if there are not too many files).

（防止上方蹩脚英语看不懂也用中文写一次）
在安装有 QTTabBar 的情况下，在任意文件夹中选中文件后，按空格，有时候会预览该文件夹中特定的某个文件；如果该文件夹中文件较多，则预览结果虽不一定都是同一个文件，但都是某几个文件中的一个。

Expected behavior
QuickLook and QTTabBar work normally and are compatible with each other.

Desktop (please complete the following information):

• OS Version: Windows 10 1909
• QuickLook Version: 3.6.9 from the msi installer

I can't reproduce this issue:

Kind of strange. It seems that this issue would not happen all the time (so I have edited the issue). Even when I try to reproduce this issue and record a GIF, I cannot reproduce this issue all the time.
Here is the GIF:

I see the selected item changed in your GIF, which seems caused by something else. You can do the follows to confirm next time when it happens:

1. Quit QuickLook.
2. Select another file and press Spacebar.
3. See if the selection goes back to the previous file.

Oh, I know why. It is because QTTabbar sees the Space as a normal search action, so it will lead you to select the next file that contains a space " " in its name. Folders in my GIF do not have any file that contains " " in names so I can't reproduce.

Is there an option to turn this feature off? -- Yes!

Enhanced incremental search in view
In short, you can find items in the view by typing on the keyboard. The system original feature matches only initials; this can matches characters in the middle of file name.

Confirmed. It is indeed not a QuickLook issue. Thanks for your help.
