IE 11 does not show all text content on P element

Hi,

I have a problem that is showing on particular IE11.0.38 on Windows 7. At least two of my friends have reported it, though I can’t see it on my IE11.0.38 on Windows 10 (installed on Virtualbox as I have Macbook).

So the problem is that the text element is showing one or two lines of the content and then gets cropped. I added a quick’n’dirty hack to check if it’s about the P or H2 element height. The hack makes the element height fixed on IE10+ because IE11 does not respect min-height (used these classes on different sized text elements):
@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
.ie-fix-1 { height: 70px; }
.ie-fix-2 { height: 130px; }
.ie-fix-3 { height: 30px; }
}

The result is that the element takes more space but the text is still not visible. I provide you URL, screenshots and login credentials in private content. First H2 shows fine but the next one doesn’t show at all. Two P elements are hidden after one or two lines.
