This task is a followup for T395820: Implementing new PatchDemo multi-environment-deletion UI. There are a couple of useful UI tweaks that could make multi-delete nicer.

See @A_smart_kitten 's comments below.

Thanks for the work that's been done on this! :)
A few notes from some things I noticed with the new UI elements (let me know if you'd like me to file any/all of these as separate tasks!):

1) At the moment, it seems like the checkboxes are slightly vertically-misaligned with the linked wiki-IDs. It also feels (IMO) like there could be a little bit of extra padding added to the right of each checkbox, before each wiki's ID:

2) When scrolling down the page, the checkboxes overlap the sticky table headers at the top of the page:

3) When hovering over the "Delete selected" link, it doesn't become underlined, which makes it feel different from the other links on the page/less like a link:

comparing this (hovering over the linked wiki ID)	to this (hovering over the "Delete selected" link)

4) My browser's developer tools complains to me that the checkbox elements don't have labels. (I don't know whether or not this presents any issues within the UI, but I thought it might be worth noting):
