ID 356441 - Hydra Viewer: *Live Render from Viewer Camera* button does not work as expected when using multiple viewports

Problem summary:

We should be able switch the camera used by the renderer in a Viewer with multiple Viewports by clicking on the Viewport that we want to take the camera from; when the "Live Render from Viewer Camera" button is selected.

Steps to reproduce:

1. Create a live-renderable scene (I use the PonySceneQA node)
2. Live Render the scene
3. Enable the "Live Render from Viewer Camera" button in a multi-viewport Hydra Viewer, where the viewports are looking through different cameras.
4. Click between the different viewports and observe the Live Render

Expected behaviour:

The camera that the Live Render renders from should update with the viewport that is last selected.

Actual behaviour:

The Live Render does not update properly.

Workaround:

Turn off the "Live Render from Viewer Camera" button and re-enable it whenever you want to change viewports.

Tested versions/platforms:

• All builds with "Live Render From Viewer Camera" feature in the Hydra Viewer are affected
