Hi webbrewers,
Sorry for the trouble caused at your end.
Per your description provided, we understand your concern and when we tested at our end by dragging the field in the Grid View of the Site Pages, I can reproduce the same behavior
as you mentioned where we can’t scroll down the page.
I have tested this behavior in both Microsoft Edge and Google Chrome browsers, where
I can repro the problem irrespective of the browser and also I can see the same behavior for updating the values by dragging in the Grid view for Libraries/Lists as well.
I understand the inconvenience caused by it
and I request you contact the SharePoint Developer team to report the problem directly who have enough resource for further investigation. Reference
article
for contacting the developer team.
In addition, as a workaround, you can drag until the end of the page and scroll down the page for updating the rest items by dragging. I understand it’s still inconvenient and we
are sorry for it.
Appreciate your understanding and patience.
Best Regards,
Ivy
