How to fit column header into narrow column?

Webix JS
1

When column width forces header text to break into two rows, the second row is not displayed even when header height would allow it

Apparently it happens because of hardcoded ‘lineheight’ for the header cell.

Is there any way around it?

Can be forced by a custom css code like follows

<style>
  .webix_hcell{
    line-height:20px !important;
    padding-top:10px;
  }
</style>
