This issue is intended to track various issues that reduce the “jankiness” of Drupal’s admin interface.
What is jank?
“Jank” is any stuttering or choppiness that a user experiences when there is motion on the screen—like during scrolling, transitions, or animations. So although a website may look incredible and load quickly, if there’s jank—a noticeable choppiness when using the page—this will negatively affect the user experience—something we all want to avoid.
Specifically within Drupal, a number of admin interfaces are janky on page load. This means that when you initially navigate to the page, it quickly loads looking one way, and then when JavaScript loads, it modifies the page to look another way.
Adding 📌 Add a placeholder preview for the navigation toolbar Active .
Note that 📌 Render the navigation toolbar in a placeholder Active gives us more options.
