[Bug] Kepler 2.5 CustomMapPopoverFactory injection props passed without context

**Describe the bug**
kepler version 2.5
On a **CustomMapPopoverFactory** injection the prop object has no data object returned based on the point clicked
no problem on the 2.4 version

**To Reproduce**
Steps to reproduce the behavior:
1. use kepler 2.5
2. create a CustomMapPopoverFactory injection
``` javascript
const CustomMapPopoverFactory = (...deps) => {
const MapSidepanel = props => {
console.log(props.layerHoverProp.data)
```

4. all the data of the layer is returned not the data specific to the point

**Expected behavior**
Data should be field with the informations specific to the clicked point

**Desktop (please complete the following information):**
- OS: Ubuntu 20.04.2
- Browser firefox
- Kepler Version 2.5

Start by reproducing the issue in Kepler 2.5 with a CustomMapPopoverFactory injection and inspect props.layerHoverProp.data for the clicked point. Compare the same behavior with Kepler 2.4; the work is done when the injected props expose data specific to the clicked point rather than all layer data.
