pseudo class with height as calc() doesn't seem to work

[Skylsmoi]

Hi,
I'm using python 3.7 and WeasyPrint==51

My issue is to render this:

.myClass::after {
    content: '';
    position: absolute;
    border: 1px solid #000;
    border-right-width: 0;
    border-top-width: 0;
    left: 10px;
    top: calc(0% - 15px);
    width: 7px;
    height: calc(50% + 15px);
    line-height: 16px;
    color: #000;
}

which, using border-left and border-bottom, should render something looking like an L.

On my html render, it works well, but on the pdf render, the border-left isn't rendered.

To fix it, I must not use the function calc() in the height rule.

It seems there is something not working with the height as calc() in a pseudo class.
The issue is the same with ::before and ::after

Hello, and thanks for your report.

calc() is not supported, that’s why it doesn’t work. This issue is a duplicate of #357.
