感谢您的报告 @Noble_Fish 👍

@martin 您对这个修复有什么看法？

>
> The admin sidebar's \`@cached\` \`sections\` getter calls \`amendLinksToSection\` on \`…AdminNavManager\`, which permanently mutates its internal \`#adminNavMap\`. When the getter re-evaluates (e.g. after toggling the \`enable\_form\_templates\` upcoming change via MessageBus), links accumulate: they persist after a setting is turned off and duplicate on repeated toggles.
> 
> This happens because \`amendLinksToSection\` pushes to the persistent \`#adminNavMap\` array, and there was no mechanism to reset it between evaluations.
> 
> The fix adds a \`resetNavMap()\` method to \`AdminNavManager\` and calls it at the start of each \`sections\` evaluation, ensuring a clean slate. This also makes the existing dedup guards (plugin link filtering, \`linkExists\` check for upcoming\_changes) redundant, so they are removed along with an unnecessary closure wrapper for login route links.
