When tapping on the earth icon, consider opening directly in the browser instead of a webview.

Expected behavior

When I open a post in the reader, and I tap on the upper right earth icon, I would expect the post to open in the device browser.

Actual behavior

When I open a post in the reader, and I tap on the upper right earth icon, the post opens in a webview and from there if I tap on the bottom right earth icon, the post opens in the device browser.

I do not have the context unfortunately of the reasons the in the middle webview is opened instead of directly going to the browser, but if we cannot figure it out it feels an unnecessary step 🤔 ...so tracking it here for consideration.

Steps to reproduce the behavior

• open a post in the reader
• tap on the upper right earth icon to open the post in a webview
• tap on the bottom right earth icon to open the post in the device browser

Tested on [iPad 7th gen], iOS [iPad OS 17.2], Jetpack iOS / WordPress iOS [23.8]

Start by tracing the reader's upper-right earth-icon action and the existing webview-to-browser flow described in the reproduction steps. Confirm how the action is implemented for iPad/iOS, then verify that tapping the upper-right icon opens the post directly in the device browser without the intermediate webview.
