Description

A clear and concise description of the problem or missing capability...

Angular pages are always LTR, even when specifying an rtl language in i18n-locale parameter

Describe the solution you'd like

If you have a solution in mind, please describe it.

When running build with i18n-locale set to an RTL language such as Hebrew or Arabic, add dir="rtl" to html or body tags in index.html.
I know that the cli can modify the html, because base-href parameter does it

Describe alternatives you've considered

Have you considered any alternative solutions or workarounds?

Manually setting the dir tag, but then what happens if I want to support different build configs for rtl, and ltr locales? I will have to manually change the dir tag before every build.

Any progress with this issue?

It would be great to have this in place, or some clarification on what's the best approach to serve an index.html that can have different dir attribute values.
