Date picker is setting incorrect date when typing manually a date that is out of range

Detailed description

Describe in detail the issue you're having.

 When typing manually a date in a date picker input field that has flatpickrOptions set to a specific range. And that date is out of the range, it is expected that the input field is reset and leave it blank. 

  However, it is changing the date to another date that is in the valid range. For example, in my testing I have a date picker with flatpickrOptions = min date -> April 1, 2021, max date -> April 1, 2022. 

  If I type manually the string 'may 20, 2022' or 'may 20 2022' , the date selected is set to 'Dec 20, 2021'

Is this a feature request (new component, new icon), a bug, or a general issue?

Additional information

Here is the code of my date picker. <ibm-date-picker [label]="'On-Demand End Date (May not exceed 1 year past the event end date)'" [flatpickrOptions]="onDmndEndDtFlatpickrOptionBuild" [attr.disabled]="enabledOnDemandDate" [placeholder]="'MMM dd, yyyy'" [invalid]="formSubmitted && !briefGroup.get('onDmndEndDt').valid" [invalidText]="onDemandEndDateInvalidText" [dateFormat]="'M d, Y'" [value]="onDmndDateInitialValue" [skeleton]="loading" id="onDmndEndDt-datepicker2" formControlName="onDmndEndDt" [attr.readonly]="!editable.user" (valueChange)="onDemandDateChange($event)"

  You can reproduce using any options for attributes 'label', 'invalid', 'invalidText', etc, only flatpickrOptions set it to: 
  onDmndEndDtFlatpickrOptionBuild = {
minDate: new Date(),
maxDate: this.addAdditionalDays(new Date())

};

addAdditionalDays(eventDate) { const endDate = new Date(eventDate); const add365Days = new Date(endDate); add365Days.setDate(endDate.getDate() + 365); return add365Days; }
