 - Fixed a bug where accessing a custom field’s magic property on an element would return the field’s raw database value rather than `null`, if it didn’t belong to the element’s field layout anymore. ([#12539](https://github.com/craftcms/cms/issues/12539), [#12578](https://github.com/craftcms/cms/pull/12578))
 - Fixed a bug where previewing an asset could wipe out all `h1` tags within Redactor fields. ([#12545](https://github.com/craftcms/cms/issues/12545))
 - Fixed a bug where `craft\image\Raster::getIsTransparent()` wasn’t working. ([#12565](https://github.com/craftcms/cms/issues/12565))
+- Fixed a bug where textual condition rules were still showing a text input when the “is empty” or “has a value” operators were selected. ([#12587](https://github.com/craftcms/cms/pull/12587))
 - Added `craft\helpers\Db::escapeForLike()`.
 - `craft\services\Assets::getAllDescendantFolders()` now has a `$withParent` argument, which can be passed `false` to omit the parent folder from the results. ([#12536](https://github.com/craftcms/cms/issues/12536))
 - Deprecated `craft\helpers\DateTimeHelper::timeZoneAbbreviation()`.
