Rich text from markdown can get newlines wrong

[drognisep]

Describe the bug:

I was following the youtube video here to make a markdown editor, and I noticed that when adding exclamation points in a header, like in "Hello!!!", the first is put on the next line, while the second and third are added to the header.

To Reproduce:

Steps to reproduce the behaviour:

Type the text as shown into the editor panel on the left.

Screenshots:

Example code:

This is the code I used to create the HSplit markdown editor. Pretty much exactly what was shown in the video except for window sizing.

package main

import (
	"fyne.io/fyne/v2"
	"fyne.io/fyne/v2/app"
	"fyne.io/fyne/v2/container"
	"fyne.io/fyne/v2/widget"
)

func main() {
	a := app.New()
	w := a.NewWindow("Markdown editor")
	w.Resize(fyne.NewSize(640, 480))

	edit := widget.NewMultiLineEntry()
	rich := widget.NewRichTextFromMarkdown("")
	edit.OnChanged = rich.ParseMarkdown

	w.SetContent(container.NewHSplit(edit, rich))
	w.ShowAndRun()
}

Hi. I have similar issues.

Also I cannot find what markdown is currently supported. Tables? Syntax Hi-lighting for code fences?

This would be a really, really useful tool if it was working properly.

Tables? Syntax Hi-lighting for code fences?

These are not part of the core Markdown spec, we may add them in the future

both items fixed on develop branch :)

If I run the above example code and type in **hello** then no emphasis is added. The emphasis only appears when I add another *. I tried looking into this myself but I'm not familiar with the inner workings of the Markdown Renderer.
