When using libxml_use_internal_errors(true), errors pile up in an internal error handler. When not resetting errors using libxml_clear_errors(), subsequent libxml usages may fail. The patch properly restores the previous libxml error handler value and clears errors.

External "enshrined/svg-sanitize" package uses `libxml_use_internal_errors()`, but fails to clear errors using libxml_clear_errors(). This can lead to side effects with subsequest libxml usages. An upstream patch to fix this is pending, but it needs to be merged and released. In the meantime, we mitigate the issue in our wrapper class.
