Mark unicode full-width space as space when "Show invisibles" is on

When editing a document with Scrivener 3, it would be great if full-width spaces were marked as spaces. They are currently invisible, which makes it hard to see if there is a space after a comma with some Japanese fonts.

See how the editor formats the following text (attached screenshot):

テスト、です。 テスト、 です。 テスト、 です。

line one: comma, no space
line two: comma, half-width space (normal space)
line three: comma, full-width space

I propose using the same mark to indicate a full-width space as is already used for the half-width space. Thank you for your consideration.

Added for 3.0.3.

All the best,

Sweet, thank you!
