When rednering the plan in the canvase view it doesn't exit the first codeblock that is rendered.

The markdown renders fine until the first code block and then after that block the reset of the file is rendered as if it is in a codeblock without proper markdown formating

Start by reproducing the issue in the canvas view with a plan containing a markdown code block followed by regular markdown, using the reported app version and GitHub theme if available. Compare rendering before and after the first code block; done means content after the block is rendered as normal markdown rather than remaining inside the code block.
