[Bug]: Chart tooltip window resizes in error

[wadhwamatic]

What happened?

If you chart tooltip window is open and you then drag the map, the window often reduces its width by half, cutting off content.

Steps to replicate:

1. Country = Cambodia
2. Open layer: Flood > Early warning > EWS 1294
3. Click on a point
4. After the tooltip window is open, drag the map

Note, I've not been able to replicate this for other tooltip charts (10-day rainfall, NDVI)

Which country / deployment are you running?

Cambodia / main

Also observed in PR 1332 when using the Google Floods layers

Add a screenshot (if relevant)

It looks like mapbox-gl is adding this automatically (on-purpose). We can prevent this by adding a max-width none !important. I'll include in #1328 👍
