TYPO3 Core

Do you have installed the extension ckeditor_fix as I did?
After deinstalling it, the backend was again scrollable.

Correction: Most right pane is not scrollable (It is not even Monday)

hi, have you installed the extension "ckeditor bugfix for #80116"

Deinstall and all is scrolling is working again, the fix is now part auf TYPO3 core

Indeed, the problem was in this fix. thank you all!

I love to work with T3bootstrap from Sven Wappler.
He fixed the old problem in an earlier version.

In ../typo3conf/ext/ws_t3bootstrap/Resources/Public/CSS/Backend/mods.css I deleted:

/* https://forge.typo3.org/issues/80116 * Bugfix for Chrome Scroll Bug
*/

html {
overflow: auto;
}
body {
height: auto;
min-height: 100%;
overflow: visible;
}

Now all is working again.

Still happening in 8.7.12 and there is no "ckeditor_fix" extension installed.

The iframe that includes an extension module is built this way:

<iframe name="list_frame" id="typo3-contentIframe" scrolling="no" class="scaffold-content-module-iframe t3js-scaffold-content-module-iframe"></iframe>

Notice the "scrolling=no". This fixes the problem:
