Steps to reproduce

• Import antd library (antd.js or antd.min.js) directly into the browser
• Set moment localization using moment.locale()
• Setup locale provider with 1 DatePicker without any defaultValue, 1 DatePicker with defaultValue, 1 Calendar without defaultValue

For DatePicker without any defaultValue:

• Click on DatePicker (Russian dates are displayed)
• Select a date
• Click on DatePicker (calendar date is still wrong)

For DatePicker with defaultValue set:

• Click on DatePicker (date is correctly displayed)
• Clear the date on DatePicker
• Click on DatePicker (Russian dates are displayed)

For Calendar without defaultValue set:

• Dates are not displayed correctly

What is expected?

• DatePicker's calendar dates should be correct when no date values has been set
• Calendar's dates should be correct when no date values has been set

What is actually happening?

• Dates are not displayed correctly (ie: they will be shown in Russian text) in DatePicker's calendar or Calendar when:
  • DatePicker or Calendar defaultValue is not set
  • When date value is cleared from DatePicker
