Temporal Controller: No option for 'Source Timestamp' in Export Map Animation settings

[LudvigForslundEEA]

What is the bug or the crash?

It seems as if the 'Source Timestamp' option is missing from the Export Map Animation settings, while it is available in the step settings in the time-slider.

Temporal Controler slider options:

Export Map Animation

As can be seen, the 'Source Timstamp' is missing from the export options, and for this particular WMTS layer I am not able to use any other settings to visualise all available time steps. The service contain layers at date 01, 11, and 21 of each month (Jan - Dec) from 2017 to 2021.

Therefore, I am adding this as a bug rather than a feature request since I assume it has simply been forgotten? Please move to 'feature request' if I am wrong.

Steps to reproduce the issue

1. Connect to WMTS service: https://phenology.hrvpp2.vgt.vito.be/wmts?request=GetCapabilities
2. Add layer CLMS_HRVPP_ST_PPI_10M
3. Open layer properties and navigate to Temporal Settings.
4. 'Dynamic temporal control' should already be activated and set to 'Automatic'. Check the 'Ignore time components (use dates only)' checkbox and click OK.
5. Open Temporal Controller.
6. Open 'Animated Temporal Navigation'
7. Animation range should already be set to '2017-01-01' to '2021-12-21'
8. Set Step to '1.000' and 'Source timestamps'
9. Click 'play' and see it works fine.
10. Open the 'Export Animation' and see that the 'Source timestamps' is missing from the Temporal Settings at the bottom.
