Dying sign text also triggers clickEvent

The bug

Dying the text of a sign additionally triggers clickEvents of the text components.

This is likely not the intended behavior because the player wanted to only dye the sign text.

How to reproduce

1. Use the following command

   /setblock ~ ~ ~ oak_sign{Text1:"{\"text\":\"Dye me\",\"clickEvent\":{\"action\":\"run_command\",\"value\":\"/say Clicked\"}}"}
   

2. Try to dye the text of the sign
   → The text color was changed but the clickEvent was triggered as well
