When using temp stream, filter convert.base64-encode omits padding
bytes.
Actually on php 7.2.1 (instead of 7.2.2 selected above) - multiple php
versions installed with brew.sh

Found a similar bug on old php version #68532
(https://bugs.php.net/bug.php?id=68532)

---------------
Please find test script (based on #68532) here:

Expected result:
----------------
encode - low-level - memory = dGVzdA==
decode - low-level - memory = test
encode - low-level - temp = dGVzdA==
decode - low-level - temp = test


Actual result:
--------------
encode - low-level - memory = dGVzdA==
decode - low-level - memory = test
encode - low-level - temp = dGVz
decode - low-level - temp = test
