Pressing `<Leader>g` causes the cursor to advance 1 character

[robinjam]

Describe the bug

Bit of a weird one. When I press <Leader>g, the cursor advances forward one character. The WhichKey pane still appears, and I can still follow up with r, d, etc., and those bindings all function as expected.

I've not noticed this issue with any other key combination (though I haven't exhaustively checked).

:checkhealth output looks fairly normal, but the WhichKey section shows this (not sure if it's an issue/related):

which-key: require("which-key.health").check()

WhichKey: checking conflicting keymaps ~
- WARNING conflicting keymap exists for mode **"n"**, lhs: **"sF"**
- rhs: ` `
- WARNING conflicting keymap exists for mode **"n"**, lhs: **"sr"**
- rhs: ` `

- rhs: `<Plug>(comment_toggle_linewise)`
- WARNING conflicting keymap exists for mode **"n"**, lhs: **"gb"**

I tried checking out the latest Kickstart master, deleting ~/.local/share/nvim and relaunching nvim, and the issue persists.

To Reproduce

1. Press <Leader>g. Notice that the cursor advanced one character, but vim is still awaiting input (and WhichKey is open).
