Anybody else having issues with Inline HTML custom entity fields within the 2021.1 Release Preview? They show up with blank content for the new Project view only. Adding buttons via User Events to sub-lists also seems to be broken for the Project Page only. I can copy the same field to another entity and it works. So just the new project page. I solved this. They changed how they present the sub-lists. They no longer come with the initial page load. It makes additional requests to load the project tasks table. So it will override your before load logic.
