Livetable select options have invalid attribute "text"

We faced an a11y issue while BITV examination (german wcag). Live tables do have the option to choose how many items per page should be displayed. These options have the invalid html attribute "text". Should be removed.

Found it on https://playground.xwiki.org/xwiki/bin/view/XWiki/USERUSER?category=groups. <--- Change USERUSER to your user.

It's all elements like: 

document.querySelectorAll("#user\\.profile\\.group\\.table-pagesize > span.xwiki-livetable-pagesize-content > select > option")
