Created attachment 112955 [details] screenshots demonstrating the bug Starting from Kubuntu Bionic LTS, Katepart doesn't highlight keywords, control words etc in bold or underline. Italic and strikeout work. I have attached screenshots from Trusty, Xenial and Bionic LTS versions demonstrating this. Further, if we select underline highlighting, even clicking on Apply clears the underline checkbox. This doesn't happen with bold but the effect doesn't get applied though it is shown in the preview in the settings.
