Yomitan does not load in Protonmail email content

This also doesn't work for me as well. The email content does not highlight nor does the popup load at all in Protonmail. However, the rest of the page, including the Protonmail email composer, scans perfectly fine.

I took a look at the DOM structure and noticed the email content is basically loaded in an . Not sure if that has anything to do with the scanning issue.</p> <p>Here are my current specs:</p> <p><strong>Browser version</strong> Chromium 118.0.5993.88（Official Build, ungoogled-chromium）</p> <p><strong>Yomitan version</strong> 24.6.17.0</p> <p><strong>Exported settings file</strong> <a href="https://github.com/user-attachments/files/15923973/yomitan-settings-2024-06-21-07-00-21.json">yomitan-settings-2024-06-21-07-00-21.json</a></p> </div> </div> <div class="comment"> <div class="user"> <a rel="noreferrer nofollow" target="_blank" href="https://github.com/ika-musuko"><img src="https://avatars.githubusercontent.com/u/32429059?v=4" />ika-musuko</a> commented <strong> 1 week ago</strong> </div> <div class="markdown-body"> <p>I think this is a related issue <a href="https://github.com/themoeway/yomitan/issues/499">https://github.com/themoeway/yomitan/issues/499</a></p> <p>I did a little bit more investigating and created a minimal example to reproduce this bug. Protonmail loads email content as a new html document in an <code><iframe></code>.</p> <pre><code class="language-html"><!DOCTYPE html> <html lang="ja"> <head> <meta charset="utf-8"> <script> function loadFrame() { const content = `<!DOCTYPE html> <html lang="ja"> <head><meta charset="utf-8"></head> <body> <div>読めない！</div> </body> </html> `; const iframe = document.getElementById("frame"); const doc = iframe.contentDocument || iframe.contentWindow.document; doc.open(); doc.write(content); doc.close(); } </script> </head> <body onload="loadFrame()"> <div>テレビです</div> <iframe id="frame" frameborder="0" sandbox="allow-same-origin allow-popups allow-popups-to-escape-sandbox"> </iframe> </body> </html></code></pre> <p>The 読めない text cannot be scanned by Yomitan.</p> <p>If you add the value <code>"allow-scripts"</code> to the <code>sandbox</code> attribute of the iframe, the 読めない text becomes scannable by Yomitan. </p> <p>Though interestingly, you cannot just hack in this value in the browser dev tools to get Yomitan scanning to temporarily work. </p> </div> </div> <div class="page-bar-simple"> </div> <div class="footer"> <ul class="body"> <li>© <script> document.write(new Date().getFullYear()) </script> Githubissues.</li> <li>Githubissues is a development platform for aggregating issues.</li> </ul> </div> <script src="https://cdn.jsdelivr.net/npm/jquery@3.5.1/dist/jquery.min.js"></script> <script src="/githubissues/assets/js.js"></script> <script src="/githubissues/assets/markdown.js"></script> <script src="https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@11.4.0/build/highlight.min.js"></script> <script src="https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@11.4.0/build/languages/go.min.js"></script> <script> hljs.highlightAll(); </script> </body> </html>
