• [x ] I have checked the superset logs for python stacktraces and included it here as text if any
• I have reproduced the issue with at least the latest released version of superset
• [x ] I have checked the issue tracker for the same issue and I haven't found one similar

Superset version

25.6

Expected results

When using a time series for a deckGL scatter plot, the "play"button should step through each time step per the defined grain.

Actual results

This seems to have worked in prior SS versions but on this version the play button is static on 1970 and as such, there is no step by step animation:

Steps to reproduce

Create a Scatter DeckGL chart with a well defined time grain, try to use the "play" button to traverse through each step.
