Unable to change fonts with TinyMCE inside Enhanced Content Editor (ECE)Issue Custom fonts added via the system property glide.ui.html.editor.v5.font.collection do not appear in the TinyMCE Editor toolbar font dropdown within the Knowledge Center workspace (Enhanced Content Editor v5). EXAMPLE A custom font (e.g., "Open Sans") is added to the system property: glide.ui.html.editor.v5.font.collection >>> Open Sans The system property accepts and stores the configuration, but the font does not surface in the font dropdown list when editing Knowledge Center content.ReleaseAll releasesCauseThe Enhanced Content Editor v5 uses a custom TinyMCE implementation. The toolbar font dropdown is not wired to read the custom font collection from glide.ui.html.editor.v5.font.collection. This is the current design behaviour.ResolutionThis is a design limitation of the Enhanced Content Editor v5 in Knowledge Center. Custom fonts configured via a system property cannot currently be exposed through the TinyMCE toolbar dropdown. Status: This is an enhancement consideration for future iterations of the Enhanced Content Editor. Workaround: None currently available through the UI. Custom fonts may be applied at the platform level through alternative methods (e.g., CSS customisation, theme modifications) depending on your environment.
