AbstractPdf - ZendException font is not set

[jchenevey]

Preconditions

1. Magento v2.2.0
2. PHP 7.0.22

Steps to reproduce

1. Try to write a large multi-line block of text using drawLineBlocks() (my apologies for not providing a better example here - this came up during development of a custom module, which I am unable to include here)

Expected result

1. PDF should render

Actual result

1. A new Zend_Pdf_Exception is thrown, stating "Font has not been set"

The issue is caused by lines 1034-1036 in /vendor/magento/module-sales/Model/Order/Pdf/AbstractPdf.php.

foreach ($column['text'] as $part) {
    if ($this->y - $lineSpacing < 15) {
        $page = $this->newPage($pageSettings);
    }
...

This new page is created after the font has been determined (lines 1008-1025) and set for the line to be written. Therefore, at the time line 1057 is reached (below), the font for the new page has not been set.

$page->drawText($part, $feed, $this->y - $top, 'UTF-8');

The solution would be to re-set the page's font after creating the new page.
