Don't override CSS direction in code elements

[ffoodd]

Fixes #35219

RTL users can now use the dir attribute if they need to display LTR code, but we don't assume this as a default anymore.

Makes sense, some others tweaks can be done afterward but this should be done first and as soon as possible.

Thanks! Could you elaborate why unicode-bidi: isolate might be a better option than dropping it entirely? The Webkit issue you linked does not make much sense to me.

Can we have this first in then discuss that if necessary? I really didn't want to open the discussion for it here, what I really meant isolate is just better than bidi-override and didn't oppose removing this altogether. I thought that was the original intention that's why I went for it initially.

The Webkit issue you linked does not make much sense to me.

The attached image in the WebKit bug shows the issue, to recreate it here say someone writes the following,

Abcasd <code>"شسی"</code> = <code>$1</code>

It will result in:

Abcasd "شسی" = $1

But using isolate or something alike turns it to this which obviously is the intention:

Abcasd "شسی" = $1

Ofc whether unicode-bidi: embed; should be used here or unicode-bidi: isolate; can be a bit controversial (but both are good, better than bidi-override or not setting it) but bootstrap can always hand the decision about it to the clients.
