Font size in the rationale dialog

[AndreyFetisov]

Please reduce the font size in the rationale dialog and align the text to the left. The text does not fit on the screen.

Same here, rationale dialog font size is too big. If the user using a bigger system font the rational is too big.
Otherwise when i want to use a own RationaleDialog its not possible to set the Text/Message. Its only possible to set a title.
