**[Affected versions]:**
- Firefox Nightly 70.0a1, Build ID 20190805095413

**[Affected Platforms]:**
- All Windows
- All Mac
- All Linux

**[Prerequisites]:**
- Have the `browser.newtabpage.activity-stream.asrouter.devtoolsEnabled` pref set to `true`.

**[Steps to reproduce]:**
1. Start the browser with a new clean profile.
2. Open a new profile and trigger the Special Monitor snippet.
3. Resize the Browser window to half screen and observe the snippet.
4. Resize the Browser to the minimum width and observe the snippet.

**[Expected results]:**
- Step 3: The "x" button is displayed outside of the snippet area.
- Step 4: Most of the message is displayed outside of the snippet area.

**[Actual results]:**
- Step 3 & 4: The snippet is resized accordingly.

**[Notes]:**
- The issue is also reproducible with Discovery Stream on. But in this case the Snippet should not be resized as the whole page does not support any other browser size.
- Attached a screen recording of the issue.
