Tab size preference not respected in Markdown code blocks, still uses default 8 characters.

Body

Tab size preference setting doesn't affect code blocks inside Markdown files, they still show with a width of 8 characters with no clear way to change this.

And I'm not talking about code editor, but the preview, ie. when you open the repository and scroll the README, the code blocks use 8 characters for tabs.

Accessibility issue: users have to press shift + scroll to see the long code due to 8 character tabs. which may not be possible to people with a disability.

Hello @rehhouari - we wanted to follow-up on this reported issue. Have you tried modifying the indent mode and size on the markdown file as shown in this screenshot? Does this feature help resolve your issue?

[rehhouari]

Hi, this option is only for editing, when viewing any README, even when logged in, it's always 8 characters per tab, regardless of Settings > Appearance > Tab Size Preference.
Thanks for the reply

Hey everyone! I'm excited to announce that we've recently fixed this issue by making user-defined tab-width preferences consistent across GitHub (see changelog here). Feel free to test this out and drop a comment in our community discussion if you have any feedback or run into any issues.
