Characters that appear unexpectedly narrow

The following characters appear unexpectedly narrow:
‧ U+2027 Hyphenation Point
∘ U+2218 Ring Operator
⋅ U+22C5 Dot Operator
⸱ U+2E31 Word Separator Middle Dot

These characters also appear narrow in any other of the few monospaced fonts that I tried (Courier, Consolas, Cascadia Mono, Lucida Console), so there may be a common reason.

I tested rendering these characters with Visual Studio Code and Windows Notepad. All listed characters appear narrow on both.
