Merge Risk: 🟡 Moderate · up to This change fixes the reported bug where images were lost when clipboard content had both text and an image, but it introduces a related regression: clipboard content with an image and no HTML (or an image followed by caption text) can now cause the accompanying text to be silently dropped during paste. This should be addressed before merge since it can cause visible content loss for common copy-paste scenarios. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Preserve text when the clipboard also contains one image.
shouldUploadFilesOnly returns true for empty HTML without checking text/plain. It also ignores text nodes after an image because childElementCount counts only elements. onCapturePaste then uploads the files and returns before calling onPaste, so the text is lost.
Pass text to the helper and require both plain text and parsed HTML text content to be empty before selecting the file-only path.
