Element active in recents from "share" action wipes composer on every re-focus

#### Describe the bug
When sharing something to Element (a link), going to a different app, and then returning, it wipes the composer of any additional text.

This is likely due to the Share Activity or Intent being "front-ed" onto the recents view, which then gets re-activated every time it's returned to.

#### To Reproduce
1. Go onto a website in the browser.
2. Share to Element
3. Type something next to the URL in the composer bar.
4. Go to other app via Recents.
5. Go back.
6. Observe Composer being wiped.

#### Expected behavior
The composer not being wiped.

#### Smartphone (please complete the following information):

- OS: Android 10, ColorOS v7.1 (it uses it's own recents view impl)

#### Additional context
- App version and store: Play Store, 1.1.3
