skipping function triggers conditional command blocks

1. Create file data\functions\test\test.mcfunction with

   say Test
   

2. Place a command block with

   /function test:test if @p[tag=test]
   

3. Place a conditional chain command block behind it with

   /say success
   

4. Power the first command block

No player has the tag test, function will skipped
expected: nothing happens
happens: "[@] success"
