Command block output not showing in chat even though i have enabled it

I expected it to show the outputs again one i did /gamerule commandBlockOutput true
i thought it would show it again

Steps to Reproduce:
1. Type /gamerule commandBlockOutput false
2. Type /gamerule commandBlockOutput true
3. Try to use /say in a command block or say something in chat and it will not show up.
