Like button: not working by default on in-app browsers on iPhone & Brave browser

Hi Jetpack mechanics, just wanted to give a heads up about the Like button in Brave. There's probably not much that can be done. It's likely because of the cross site scripts that Brave disables because if I go to https://wordpress.com/read, even with Brave shields on, I can click the star button on the articles and the like is applied correctly.

#### Steps to reproduce the issue

1. Using the [Brave browser](https://brave.com/), go to https://elio.blog/5-free-styles-for-capture-one/
2. Click the Like button at the end of the article
3. a popup shows up briefly and the like is not applied
4. disable Brave shields in the site
5. once the page reloads, click the Like button again. This time the like is applied


#### What I expected

The Like to be applied.

#### What happened instead

A popup shows briefly, and the Like is not applied.
