It seems that otherwise, it is possible for a line break to occur just between the link text and the circle.
According to https://github.com/typst/typst/discussions/4372, adding the Unicode word join character is the way to forbid breaking at a specific breakpoint. I'm not totally sure both of these are needed: For the specific link where I found this issue, the character in the second position was sufficient to avoid the line break.
