Web Accessibility Issue on the Setting Page

Hello! I am currently evaluating your plugin to add to my WordPress site. I noticed that while most of the plugin works fine, there is one section of the setting page that does not meet web accessibility. Specifically, I can not focus or tab on the different setting page links. I have to use my mouse to click "Style" to get to the Style page (instead of just tabbing over and then pressing enter).

Could you make those options "tab-able"? This bug would prevent for example a non-sighted user from accessing anything other than what's on the Options page.

Thank you for your time!
