Does TextService:GetTextSize Obey Rich Text?

If you didn’t know, there is a service called TextService which has a function called :GetTextSize(). What that function does it that it tells you the dimensions of the area that the text will occupy.

Now that we have Rich Text in the game, we can use HTML tags like <i>apple</i> to turn the resultant string from apple to apple (it got italiszed).

However, does the TextService:GetTextSize() obey the rich text? Does it ignore the <i>sample text</i> tags?
