tmorehouse · web-flow · commit 6919cc5a026f · 2017-07-07T04:16:02.000-03:00
* fix(table): Remove redundant ARIA roles from table
Role `grid` and `row` are implied automatically by current table semantic markup, and not necessary.
Based on chrome Accessibility Plugin Audit  of renderd `&lt;b-table&gt;`
* fix(texts): Remove tests for b-table roles grid and row
