Nope, i didn't even noticed while working on it :D Will fix it with max height it has before

something bad with legend paddings

[propakov]

something wrong happens when open bivariate matrix

[propakov]

another moment I found
as it was a custom close button on bivariate panel, need to fix header panel position a bit

._header_pgs27_5 {
position: absolute;
right: 10px;
top: 0px;
...
}
