getHtml returns markdown

[soongsta]

Version

@toast-ui/vue-editor 1.1.1

Test Environment

Chrome, vuejs 2.6.11

Current Behavior

I am using vuejs , and npm i @toast-ui/vue-editor
Will try and setup a codepen or jsfiddle, but not familiar how to do this.

When i format a single word with bold, it works fine.
getHtml returns eg <strong>Bolded</strong>

When i format a second word with bold, and look at html (using getHtml), the 2nd bolded word is in markdown eg
**Bolded**
This applies for Italics and Strike Through as well

Expected Behavior

All words formatted should be return HTML when using getHtml function

Same problem, i tested different get method and i found this:
replace invoke('getHtml') by invoke('getMarkdown').
That return text formated in html, i don't know why
