Add a grouping per month in the chart/filter widget that truly groups per month, meaning a fixed time frame for each month regardless of other filters

I have a Line Chart widget where I want to see the count of features per month. For this, I have set the 'Category type' to 'By group' with a date column as the 'Category field.' The interval for the time binning options is set to 1 month.

The expected behavior is that the data is categorized per month, so if there are 10 features in January, the value for the label 'January' should always be 10. However, this is not the case currently. For example, when I look at all values from January 1, 2021, the value for November 2022 is 686.

Now, I am only adjusting the starting value, specifically from January 1, 2022. This should not change the value for November 2022. However, this value now jumps to 719.

The reason for this is that behind the scenes, the time frame is changing. In the first case, it is from November 4 to December 3, and in the second case, it is from November 3 to December 2. The expectation is that this time frame is fixed from November 1 to November 30 (since grouping is done per month).

The concrete idea is therefore to add this option: a grouping per month that truly groups per month, meaning a fixed time frame for each month regardless of other filters.

What are your Interval Alignment and your Trim incomplete interval settings set too?

Interval alignment is set to “Snap to the first data point”, but switching to “Snap to the last data point” does not lead to what I want either.

Trim incomplete interval is switched off.

I ran into this issue and I'm not sure how I fixed it awhile ago. From what I can remember, I republished my layer and then I adjusted the Timeline widget settings.
