I posted about this here but based on the lack of response I’m assuming there is no way to do this currently.
Basically, when you have a block that renders itself completely as a link, there is no way to directly click into the block (e.g. in order to copy the underlying text, press return to create a new child block etc), because as soon as you click on the block, you follow the link to its destination.
The default behavior should remain, but there should be a modifier key that allows you to click into a block without following a link. It could work similar to how shift + click allows you to open a page in the side panel instead of the whole pane, except with a different modifier key.
