Keyboard text not collected in Web Browsers

[ChristopherBull]

Problem description:
Using the "Keyboard sensor", text is collected when typing into native Android applications, but text is not collected when typed into a website using Android's Chrome.

When using Chrome, text typed into the address bar (potentially an Android native TextView UI element) is collected correctly. However, text typed into a webpage (e.g., an <input> element) is not collected.

At first I thought it was a Native UI vs HTML UI problem/difference, but I tested in the latest Firefox too and text is collected and reported correctly when typed into a webpage (however, surprisingly, it is not collected when typed into Firefox's address bar).

Expected behaviour:
Collect all text typed into all Android browsers.
