Scroller scrolls up automatically while trying to select an expiry date for public link

[sushmita56]

Steps to reproduce

1. First of all reduce the screen resolution
2. Log in to the WebUI and create a resource
3. Then, create a public link for the resource
4. And click on the public link edit button and then click on the Add expiration date option
5. Leave year and month as it is and now try to set the expiration date to the very last date of the month like 28/29/30/31

To select the last date of the month you'll have to scroll down. Whenever you scroll down and are about to click on the date, say 30, the scroller scrolls up automatically.

Discovered such behavior while working on the issue: #7320

Actual behaviour

The scroller moves up instantly as we hover over the date.

Expected behaviour

Unless we select the date the scroller was not assumed to shift upward.

Phew, at a first glance, the v-calendar lib which is used here does not provide any options to prevent this from happening. One easy solution would be to place the calendar always at the top. What do you think @tbsbdr ?
