I left one comment recommending a follow-up bug. modules/jfx.incubator.richtext/src/main/java/jfx/incubator/scene/control/richtext/model/RichTextModel.java line 482: > 480: if (ix < toSplit.length()) { > 481: String s2 = toSplit.substring(ix); > 482: insertSegment2(i, s2, > RichUtils.filterOutNodeAttributes(a)); This (along with the later fix in this file) looks like it will handle the important case of text insertion not getting mistakenly styled with the EMBEDDED_IMAGE style. I don't think it will handle the case of calling `insert` or `applyStyle` programmatically, though. Since that would be an application error, it seems fine to do it as a follow-up bug. ------------- Marked as reviewed by kcr (Lead).
