Description Gérard Talbot (no longer involved) 2011-04-10 02:44:22 UTC
Version:           4.6.0 (using KDE 4.6.2) 
OS:                Linux

Similarly to font-size (see bug 113728), Konqueror 4.6.2 can not render appropriately a testcase where line-height has a value lower than 3px or 2pt.



Reproducible: Always

Comment 3 Gérard Talbot (no longer involved) 2012-06-20 19:07:29 UTC
The bug still happens in Konqueror 4.8.4, 
with the KHTML rendering engine and 
when rendering engine mode (View/View Document Information Ctrl+I/ Rendering mode) is "Strict" (web standards compliant rendering mode).
