Share link menu disappears when setting expiration date

[linucksrox]

When opening the shared link menu and then opening the date picker and then clicking the left arrow to go back one month, the share link menu disappears and you lose context of what was happening, also making me unsure if the date I'm going to pick will actually save. It actually does save, so that's a bonus.

GitMate.io thinks possibly related issues are #4525 (Expiration date of shared links is not set even when it's forced), #4739 (Sharing with users disappear after link creation), #11710 (Setting start dates for shares (similar to expiration dates)), #9510 (Share link suggestion: default expiration date and maximum expiration date), and #4078 (sharing by mail doesn't allow password, expiration date, secure drop).
