sap.m.DatePicker hide or adapt calculation of the weeknumbers

OpenUI5 version: 1.101.0

Browser/version (+device/version): Chrome

Any other tested browsers/devices(OK/FAIL): OK

URL (minimal example if possible): https://sapui5.hana.ondemand.com/#/entity/sap.m.DatePicker/sample/sap.m.sample.DatePicker

User/password (if required and possible - do not post any confidential information here):

Steps to reproduce the problem:

1. Go to url
2. Open datepicker by clicking on the icon in the inputfield
3. See weeknumbers at the left side of the datepicker popup

What is the expected result?
The expectation here is that we want to be able to either hide or adapt the weeknumbers.
It's not possible to hide it. Nor is it possible to change the calculation.
There are two ways of calculating the weeknumbers, which is decided by the browser language.
But if the browser language is different than the way the weeknumber is calculated, we see a 'wrong' weeknumber.

What happens instead?
No customizing possible. Different browser languages see different weeknumbers.
