Why do styles crash in explorer 11?

Question

css

There is a site creat-web.ru/prof-edu
when first loaded in explorer 11, the styles of drop-down menus are as it should be joxi.ru/p27bPvaSog0KNm, but if you refresh the page and then look at the menus, incomprehensible elements appear joxi.ru/brRQZGzfJzQ7VA + height li increases
list-style-type: none initially spelled out for the entire site (
not understandable magic)
who can come across this and what to do?)

Answer 1

By the way, it turns out that this is one of the popular bugs - type in Google "ie11 list style bug". On SO they say that the solution might be this:
or that:
list-style-image: url(data:0);
