Equipment schedule date tooltips count certain dates twice

Ignition
1

I noticed that the labels and their tooltips don't line up for some days in my Equipment Schedule when the zoom level is set to Day. They appear to be offset by one day, as November 4th 2024 is shown as November 3rd, the 5th as the 4th, and so on. This is on Ignition 8.1.45.

Nov 2 2025, Nov 3 2024, Nov 5 2023, Nov 6 2022, and Nov 7 2021 are all double counted this way.

Conversely, March 9 2025, Mar 10 2024, Mar 12 2023, Mar 13 2022, and Mar 14 2021 are all not counted, so for very long schedules this drift does not occur. This only occurs if the previous double-counted November date is part of the date range (so all these days will be counted as expected if, for example, the date range is March 1 to March 31).

This happens with an unmodified Equipment Calendar but for convenience and sanity-checking the JSON for my minimal reproducible example is below:
