The new styling for the inline code and code blocks were looking less
than stellar in the comment bubble tooltips. The borders on both were
too light, making them appear a bit fuzzy, and the code blocks were
offset incorrectly.

This updates the styles to provide a better overall look in both the
draft and published comment tooltips.

A future change will redo the style of the tooltips to improve their
overall readability.

Tested inline code and code blocks in both draft and published

comments.
