ElementUI: el-table__fixed height change

I have a weird problem with ElementUI's el-table element. My table renders just fine, but when I navigate to another route and then come back to the view with my table, the height of the el-table__fixed-element has decreased by 17px.

Can anybody tell me what I am doing wrong? Or is there a bug in ElementUI?

Solution

I figured it out!

While inspecting my app with the Vue DevTools, I saw that my ElTableBody was rendered twice. After some searching, I found this Bug Report. Turns out, the problem was setting fixed to true on my ElTableColumn elements. After removing the fixed prop, everything renders just fine - even when returning to my view.
