All tickets related to item placement in the Creative inventory are valid for cases introduced in 1.16 and later as per this comment. Exceptions exist, which are valid for their own reasons. This ticket in specific should be valid as explicit changes were made to the Redstone tab in 1.17, which is after 1.16.

The bug

The string item is found in the Miscellaneous creative tab, despite string being placed to become tripwire like how redstone dust is placed to form redstone wire. As tripwire is a redstone component and tripwire hooks are already in the Redstone tab, it'd be expected they would appear in the Redstone tab rather than in an obscure other tab.

How to reproduce

1. Open the Creative inventory
2. Locate String in Miscellaneous
3. Locate Tripwire Hook in Redstone
4. Note that these two items have joint redstone functionality
5. Note that only one of these is in the Redstone tab
