Tab triggers blur event for every loaded VueDatePicker

[LarsEasy]

Describe the bug
When pressing the tab key, every loaded VueDatePicker will emit a blur event.
Noticeably, this does not happen if teleport is set to true.

To Reproduce
Steps to reproduce the behavior:

1. Place several instances of VueDatePicker in a vue component
2. Load the page and press tab
3. Notice all instances without teleport=true emit a blur event

Expected behavior
Blur events should not be fired from VueDatePickers if they were not in focus.
