Bulk Share Items Limitation?

I have a folder with well over a thousand items and I am trying to Select All > Share Selected … to a Collection, however it seems that only about two-thirds of the Items end up being shared.

This happens even when I scroll down to the bottom of the page, allowing all the items to populate the page. After selecting Select All I can scroll down the page and see where the Item tick boxes suddenly are no longer ticked.

I contacted Bitwarden support about this and received the following reply:

With a high volume of entries we recommend doing the share in smaller batches or using the CLI tool, there is a share function to accomplish this: https://bitwarden.com/help/article/cli/#share

Sorry but I find this answer pretty lackluster. There is obviously a bug in the “Select All” feature which doesn’t allow it to select all Items listed.
Also how exactly does one use the CLI tool to share hundreds of Items at once?
