Can't change font in textarea of `Find in Path` dialog.

OS: Window 10 x64
WebStorm: 2017.2.3
WebStorm Settings:
  Appearance - Override default fonts by - Name: Segoe UI - Size: 12
  Editor - Font:
    Font: Source Code Pro Semibold
    Size: 14
    Line spacing: 1.0
    Fallback font: DengXian (Chinese font name)
Color Scheme Font: use default
Console Font: use default

The font is always SimSun(Chinese font name) in textarea, when I use `Find in Path` command.
The case occured when WebStorm start using version `year.x.x` formated.(maybe)
