Internet Explorer is only showing 11 Months

I have a gantt chart that is displaying a task that is 13+ months long. When i load the grid in Firefox the task is fully displayed. In IE the the gantt chart only loads 11 months.

I have the gantt chart displaying in 15 minute intervals with the following settings

gantt.config.smart_rendering = true;
gantt.config.smart_scales = true;
gantt.config.fit_tasks = true;
gantt.config.static_background = true;
gantt.config.show_task_cells = false;
gantt.config.branch_loading = true;

gantt.config.scale_unit = ‘hour’;
gantt.config.step = 1;
gantt.config.date_scale = ‘%M %d’;
gantt.config.min_column_width = 50;
gantt.config.scale_offset_minimal = false;
gantt.config.subscales = [
{unit: ‘minute’, step: 15, date: ‘%H %i’}
gantt.config.round_dnd_dates = true;
gantt.templates.date_scale = null;

Im sure it a optimization thing for IE, but is there a way to turn it off?

Thank you.

I reproduced the issue in the snippet and reported the dev team about it. They will check what might be wrong there. If they find a bug, it will be fixed in future updates.

Is there any update to this item?
Thank you.

Hello Glenn,
Unfortunately, there are no updates. But don’t worry. I will mention here after the bug is fixed.
