Answering my own question, helped by @neotechnomad’s link to How to enable RTL in WordPress:

Navigate to Settings => General in your WordPress dashboard and select the preferred “Site language” – don’t forget to hit the “Save Changes” button. WordPress detects whether your chosen language is a RTL language and when your WordPress theme supports RTL, the rtl.css stylesheet is loaded automatically and your website will be displayed in RTL.

What I’m reporting is not a problem in Contact Form 7, nor a lack of understanding how to set up a telephone field in that plugin.

It is, in fact, an error of omission in the Edin theme. The theme builders accommodated all the new HTML5 selectors except “tel”.

I’ve fixed this in my local css but am pointing out the problem, so that it can be fixed in the released code.

I suppose my question wasn’t phrased well enough. I’ll give it another try.

I am not asking about the text editor. I am referring to viewing mode.

When a page is viewed in Edin, the active stylesheet is style.css. Therefore, when viewing content that is written in an RTL language such as Hebrew, the content is incorrectly aligned to the left.

As a site builder, I notice that the theme includes a stylesheet named rtl.css in the same folder as style.css.

When building an RTL site, what do I need to do to make rtl.css get picked up as an active stylesheet?
