Bug description

Hi team,
I just created an internal share to Fabien, I am trying to set an expiration date, but as soon as I've ticked the box, the tick disappear. If I click the cross to exit the share properties, the attached msg is displayed

Steps to reproduce

1. create an internal share from the desktop client.
2. enter the options, and try to set an expiration date.
3. the tick disappear, and if you close the share options, a msg is displayed : expiration date is in the past.

Expected behavior

I should be able to set an expiration date. a date picker should open, or a default value in the future should be set.

reproducible by web UI
most likely a regression of #42660
I tested using v26.0.11 and can reproduce (desktop client and web UI)
I then reverted the backport to stable26 (i.e. a31b1c7) and it fixes the bug
