Code blocks does not preserve TAB when loading Markdown

[jodator]

I was pasting code from my IDE to a suggestion:

	 *
	 *		const modelRoot = editor.model.document.getRoot();
	 *		const firstCell = modelRoot.getNodeByPath( [ 0, 0, 0 ] );
	 *		const lastCell = modelRoot.getNodeByPath( [ 0, 0, 1 ] );
	 *
	 *		const tableSelection = editor.plugins.get( 'TableSelection' );
	 *		tableSelection.setCellSelection( firstCell, lastCell );
	 *
	 * @param {module:engine/model/element~Element} anchorCell
	 * @param {module:engine/model/element~Element} targetCell

And the tabs characters were changed to spaces. This may break code style if such a suggestion is applied.

ps.: I had to switch to markdown to create this post ;)

Confirmed. This is generic to code blocks, not only suggestions.

Can you just confirm the following?

1. When pasting in the rte editor, the tabs are there, as expected.
2. Switching to the Markdown editor, the above tabs are still there, as expected.
3. Switching back to the rte editor, tabs are transformed to spaces. (issue)

Thanks!

@fredck I thought it removed the tabs on the first paste (when editing a suggestion in PR) but I can't reproduce it. However, I can confirm the case you described.

I agree that if you paste tabs into a fenced code block, they should stay as tabs. However I wish that this extension had a different but related feature: I'd like a setting such that when I type tabs in a fenced code block, they get converted to spaces, just like in all my text editors and IDEs. Is this possible?
