Desired behaviour:

Proposed fix:

1. Add to ux-checkbox.css:

[dir="rtl"] .ux-checkbox .ripple { right: -13px; }

[dir="rtl"] .ux-radio .paper-ripple { right: -13px; }

[dir="rtl"] .ux-radio .ripple { right: -13px; }

Also possible to fix it adding direction: ltr !important; rule, since it has a symmetric glyph.
