Strange behaviours of slurping streaming input without line terminators at the end

[itchyny]

Describe the bug
When the input steam has no line terminator (and space) at the end, the combination of --slurp and --stream flags behaves oddly.

To Reproduce

 $ printf "[1]\n" | jq -c -s --stream .
[[[0],1],[[0]]] # ok

 $ printf "[1]" | jq -c -s --stream .  
[[[0],1]]
[[0]] # unexpected

Expected behavior
The second command outputs as same as the first command.

Environment (please complete the following information):

• OS and Version: not related
• jq version: 1.7.1 (and 1.7, 1.6)

Additional context
This is a close issue of #1534 but with the streaming parser flag.
