GithubMarkdown not parsing inline code when there are square brackets around it

[cornernote]

echo (new \cebe\markdown\GithubMarkdown())->parse('[`code`]');

Expected Output:

[code]

Actual Output:

[code]

reference from:
cornernote/minetest-bower#29

This happens because [ marks the start of a reference. If the reference is not found, it is replaced with its original text, which is printed unparsed:

markdown/inline/LinkTrait.php

Line 224 in 2c368a9

return $block['orig'];

The fix should be to parse the content and render its absy as it is done when the link is created:

markdown/inline/LinkTrait.php

Line 229 in 2c368a9

. '>' . $this->renderAbsy($block['text']) . '</a>';

Same issue exists for images:

markdown/inline/LinkTrait.php

Line 238 in 2c368a9

return $block['orig'];

Here are some failing tests:
