MarkdownTextBlock doesn't support Multi-Line Formatting

[WilliamABradley]

I discovered while working on #1116 that the MarkdownTextBlock will not format text when symbols are used across multiple lines, such as,

**Line 1
Line 2
Line 3**

Should produce
Line 1
Line 2
Line 3

However,
it just ends up printing the asterisks straight to the screen:

Not sure if bug or per design. ping @deltakosh

It is by design :)

[WilliamABradley]

@deltakosh Http://Github.com/ and http://dillinger.io/ and http://markdownlivepreview.com/ and http://Trakt.TV/ all seem to think this is valid Bold Text? Would it be possible to have a Property to enable this as Valid Markup?

@WilliamABradley I think it is not written in the Markdown Cheatsheet so here is the confusion. This exceptional example is difficult to exploit because there is many possibilities to implement it.

Even if that's not optimized, you can still do this, no?

**Line 1**
**Line 2**
**Line 3**

[WilliamABradley]

@Odonno you could do that, however, it would damage the reversibility of the TextToolbar.
Also other websites seem to think it is to spec, therefore if we want to have a Universal Markdown control, should we support this apparent standard?
Otherwise websites that this might be used on will have broken formatting if people decide to do this.

My 2 cents: It seems even GitHub is moving toward the CommonMark Spec which support this behavior, so it might make sense to support the behavior here as well

[WilliamABradley]

Anything being done here?
@QuinnDamerell What are your thoughts?
This Control should support other Markdown Specs shouldn't it?
I would think something like this covers a lot of usage across many websites.

[nmetulev]

If someone wants to pick this one, feel free. Agree that the control can use improvement.

Can close this issue

It does seem to work now :) I don't remember when/how this was fixed and by who, but I'm glad it was!
