Preview panel won't update on redeployment

[filippsen]

Environment/Browser

Version 1.5.0

Description

Upon redeployment, the Preview panel won't update.

Steps to reproduce

1. From Hello World template
2. Open HelloWorld.sol
3. Click Deploy
4. Open Preview panel
5. Confirm it is working as intended
6. Set line 7 in HelloWorld.sol to message = "another message";
7. Save and click Deploy
8. Observe the Preview panel

Expected result

Expected the Preview contents to automatically reload after deployment. Previously, the work flow was to switch over to another window (tab), and it would then be rendering the latest contents without requiring manual intervention.

Actual result

Preview panel won't update automatically. The panel must be closed and reopened in order to see the new deployment.
