bug #34449 [Yaml] Implement multiline string as scalar block for tagged values (natepage)
This PR was squashed before being merged into the 3.4 branch. Discussion ---------- [Yaml] Implement multiline string as scalar block for tagged values | Q | A | ------------- | --- | Branch? | 3.4 | Bug fix? | yes | New feature? | no <!-- please update src/**/CHANGELOG.md files --> | Deprecations? | no <!-- please update UPGRADE-*.md and src/**/CHANGELOG.md files --> | Tickets | Fix #... <!-- prefix each issue number with "Fix #", if any --> | License | MIT At the moment you can parse a tagged value defined as a scalar block. But you can't actually dump a multiline string as scalar block when using a tagged value. This PR implements the multiline string as scalar block for tagged values as well.
