i am using the LengthAndCharacterRestriction class indirectly via setInputRestrictions() to filter my TextEditor.

When i enter text and select it being the caret at the left position of the text and i press any of the filtered keys eg. Spacebar then a) the text get’s removed and b) the caret doesn’t go back to the correct position.
i expect that when any of the filtered, not allowed keys is pressed, the selected text should not be removed.
Also when i start using setInputRestrictions i get a leak detection error when i quit the application:
*** Leaked objects detected: 1 instance(s) of class LengthAndCharacterRestriction
JUCE Assertion failure in juce_LeakedObjectDetector.h:104
Also when i reset the filter i still get leaks on quit:
PropertyTextEditor::~PropertyTextEditor() {
// Clear input restrictions to enforce cleanup
setInputRestrictions(0, {});
}
