Conditionally enable double key logic according to:
private browsing mode or privacy.thirdparty.isolate preference and
implement in GetCookieStringCommon and FindCookie where it counts...
With some reservations of how to convince FindCookie users to test
condition and pass a nullptr when disabling double key logic.

15 /** \class SkTextBox
17 SkTextBox is a helper class for drawing 1 or more lines of text
18 within a rectangle. The textbox is positioned and clipped by its Frame.
19 The Margin rectangle controls where the text is drawn relative to
20 the Frame. Line-breaks occur inside the Margin rectangle.
22 Spacing is a linear equation used to compute the distance between lines
23 of text. Spacing consists of two scalars: mul and add, and the spacing
24 between lines is computed as: spacing = paint.getTextSize() * mul + add
