System Information
Operating system: Windows 7 (64 bit)

Broken: 2.80, 69b2f5268114, blender2.7, 2019-02-10, as found on the splash screen

Short description of error
window_manager.invoke_popup() ignores preferences.view.ui_scale (window_manager.invoke_props_dialog() respects it).
In other words, the size of dialogs created with window_manager.invoke_popup() doesn't scale with the rest of the UI.

Exact steps for others to reproduce the error
Open the attached file

and run the script. Then change use_popup in the script to True and run again.
The size of the displayed dialogs (apart from the extra "OK" button) at a given UI scale should be the same, but it isn't.

@dima glib (dairin0d), could you add one or two screenshots please? I see an issue where the checkbox suddenly gets larger when I click it, but I'm not sure if we are talking about the same thing.

I'm talking about the size of the dialog box (width, height).

In the attached illustration, the width of the invoke_popup() and invoke_props_dialog() is the same at ui_scale = 1.0 ("Resolution Scale" in user preferences).
However, when ui_scale is not 1.0, the invoke_props_dialog() scales accordingly while invoke_popup() does not. E.g. at ui_scale = 2.0 the dialog created by invoke_popup() is half the size of the invoke_props_dialog().

It's just a matter of (width, height) arguments of invoke_popup() not being multiplied by the ui_scale.
