Gantt Chart Relative Duration "week" does not honor Excludes

[SethRobertson]

Specifying "Excludes Sunday, Saturday" in a Gantt chart and then using a relative duration of a week does not yield a sane result.

Example configuration file:

gantt
    title Example
    dateFormat  YYYY-MM-DD
    Excludes Sunday, Saturday
    Task1  :a1, 2021-01-11, 1w
    Task2  :a1, 2021-01-11, 5d

• Expectation, both tasks take the same duration: 5 working days.
• Actual result, task1 takes 9 calendar days (7 working days).

I believe "durationToDate" is probably a relevant function to examine. The solution might be as simple as *5/7 the weeks and use days instead, but I have not (cannot) test that.

Still there.

gantt
    title Example
    dateFormat  YYYY-MM-DD
    axisFormat %W-%a
    excludes weekends
    Task1  :a1, 2021-01-11, 1w
    Task2  :a1, 2021-01-11, 5d
