"run_command" dialog actions don't work if chat is hidden

Dialog actions of type run_command or dynamic/run_command do nothing if chat is set to "Hidden" in chat settings.

How to reproduce

1. Enter the following command into a command block:

   /dialog show @p {actions:[{action:{command:"give @s stone",type:run_command},label:"Give stone"}],title:MC-299548,type:multi_action}

2. Power the command block

3. Click the UI button labelled “Give stone”

4. Click “Yes” to confirm command execution
   → ✔ You are given a block of stone

5. Set chat to "Hidden" in chat settings

6. Repeat steps 2–4
   → ❌ You are not given a block of stone
