mod-pagespeed and Collapse Whitespace

Today I have removed “collapse_whitespace” from “ModPagespeedEnableFilters” because I have found that this setting breaks the top navigation view of Magento using the Shopper theme. With “collapse_whitespace” enabled for example “Home > Eyeglasses > Woman’s Eyeglasses” is shown as “Home Eyeglasses Woman’s Eyeglasses”. The “>” is missed – but I have no idea why. That’s strange 🙁
