Hours not taken into account

[JuGid]

First, this library is really fantastic and fit most of my use cases.

While I'm waiting for this PR to be merged (#528), I just prepare my tasks to welcome it.
This is how my tasks are :

let tasks = [
    {
        id: 'XXX',
        name: 'Programmation bas niveau',
        start: '2025-01-01T09:00'
        end: '2025-01-01T15:00'
        group: 'Programmation bas niveau'
    },
    /...
]

The starting time (09:00:00) is taken by Frappe/Gantt, but the end time isn't (15:00:00), so my Hours view is useless since Gantt make it ends at the end of the day.

This is my Gantt init :

let gantt = new Gantt("#gantt", tasks, {
    infinite_padding: false,
    view_mode_select: true,
    date_format: 'YYY-MM-DDTHH:mm',
    readonly: true,
    scroll_to: 'start',
    popup_on: 'hover',
    lines: 'vertical'
});

This is what Gantt gives me :
