Unable to remap `;` as motion key with `g:VM_custom_motions` (mapping ignored)

[SpaceShaman]

Hello!
I would like to use jkl; as my motion keys in vim-visual-multi (instead of default hjkl).
I set up the following mapping:

let g:VM_custom_motions = {'j': 'h', 'k': 'j', 'l': 'k', ';': 'l'}

or (in Lua):

vim.g.VM_custom_motions = { j = 'h', k = 'j', l = 'k', [';'] = 'l' }

Expected behavior:

• Pressing ; in VM moves the cursor right, exactly like pressing l (in accordance with documentation).

Actual behavior:

• j, k, l are correctly remapped (they move as expected),
• but ; does NOT work as motion (pressing ; does nothing or repeats previous f/t as in default Vim; it does not move the cursor right in visual-multi).

What I tried:

• Setting g:VM_custom_motions via both VimL and Lua.
• Using both ; and [';'] keys in the mapping table.
• Ensuring there is no other mapping or plugin that could shadow the mapping.
• Mapping a different letter (e.g. p = 'l') works fine, so the custom motions are picked up.

Environment:

• Neovim version: v0.11.2
• vim-visual-multi version: master
• OS: Debian 12

Summary:
According to documentation, remapping ; as a motion key is supported, but in practice the plugin ignores this mapping. All other remappings for letters work fine.
Please advise if this is a bug, or if there is a recommended workaround.

Thank you!
