Wrong foreground/text color with dark theme under frame

[ivanjx]

Describe the bug
When im using this library's dark theme (BaseDark), i noticed that text color is not converted/applied properly if the control is under a Frame (currently only textblock faced this issue). Please fix this.

To Reproduce
Steps to reproduce the behavior:

1. Apply base dark theme.
2. Add a frame under mainwindow.
3. Add a new page.
4. Add a textblock on that newly created page.
5. Load that page under mainwindow's Frame.
6. Run the app.

Expected behavior
Textblock control text color converted properly to match the theme (should be white).

@realivanjx To fix this issue just add the style to the page Style="{DynamicResource MetroPage}". This is the same WPF issue like if you want to use a default style for a Window. I can fix this only by adding the style explicit to the Page or I create a derived class like MetroPage which get's the style with the DefaultStyle key.

Is MetroPage style available on version 1.6.5? I tried but vs2017 seems to not detecting it

[punker76]

@realivanjx Yes, it's added via Controls.xaml.

[ivanjx]

Is it under this? I use this for MetroWindow but idk for MetroPage:

xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"

[punker76]

@realivanjx It's a style not a Control.

[ivanjx]

Thanks. It runs successfully and fixes the issue but vs2017 somehow throws an error:

'Page' TargetType does not match type of element 'PageInstance'

Is that normal?

@realivanjx I don't know, this is related to which VS you use and/or which SDK...
