Bug #77827
Updated by Sascha Egerer over 7 years ago
Can be reproduced in Chrome and Firefox (see Screenshot).
The @svg-tree-wrapper@ container gets a height of 5600 Pixels.
A workaround is setting a defined size for the field:
<pre>
$GLOBALS['TCA']['sys_category']['columns']['parent']['config']['size'] = 10;
</pre>
