Breadcrumbs are not readable

[SylwesterZarebski]

Userstyle: Google Dark Search
Stylus version: 1.5.6
Userstyle version: 0.7.29
Browser version: Waterfox 55, 56
Steps to reach the problem:

1. Open Google Search ie:
   https://www.google.com/search?q=test

I see:

Without dark style:

In Vivaldi page looks ok, but page is different, other language, other content - it looks like Google is serving other code for different browsers. Changing User-Agent did not fix problem.

Checked Accept-Language - is similar:
Waterfox: Accept-Language: pl,en-US;q=0.7,en;q=0.3
Vivaldi: Accept-Language: pl-PL,pl;q=0.9,en-US;q=0.8,en;q=0.7

Difference in HTML (only breadcrumb):
Waterfox:

<cite class="iUh30 tjvcx"><span class="CvmQuf">https://www.speedtest.pl</span><span class="eipWBe"></span></cite>

Vivaldi:

<cite class="iUh30 tjvcx">www.speedtest.net</cite>

Vivaldi shows very different result:

On another computer (different network) Google serve breadcrumb as:

<cite class="iUh30 tjvcx">www.speedtest.pl</cite>

Very weird. I do not know if Google will use spans in future or opposite, spans are old and previous...
