In which situation are empty text nodes added? That sounds like a potential bug. Only the start and/or end node should be splitted, and only if it is partially selected by the range. See [these lines](https://github.com/apache/incubator-annotator/blob/0821e0640a811d87f111023ee406469c0dd47deb/packages/dom/src/highlight-text.ts#L75-L90): // If the start or end node is a text node and only partly in the range, split it. if (isTextNode(range.startContainer) && range.startOffset > 0) { const endOffset = range.endOffset; // (this may get lost when the splitting the node) const createdNode = range.startContainer.splitText(range.startOffset); if (range.endContainer === range.startContainer) { // If the end was in the same container, it will now be in the newly created node. range.setEnd(createdNode, endOffset - range.startOffset); } range.setStart(createdNode, 0); } if ( isTextNode(range.endContainer) && range.endOffset < range.endContainer.length ) { range.endContainer.splitText(range.endOffset); } As discussed in issue #80, the highlighter does not run `.normalize()`, simply to not touch dom nodes when it’s not necessary. However, as written there, I’d be happy to add a few lines that undo the splitting of the start and end nodes, if any splitting happened, so that removing the highlight becomes a “perfect undo”. But again, empty text nodes should not appear due to our highlighter, so I’d be glad if you have an example case to help debugging this! -- This is an automated message from the Apache Git Service.
