Write() does not wrap if the line ends with bold text just before the specified page margin.

[DerPapst]

When a line ends just before the specified page margin with bold text, additional text appended with Write() is clipped.

Steps to reproduce this issue (include TCPDF with composer):

<?php
require_once(__DIR__.'/vendor/autoload.php');

$content = [
    ['Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy ', ''],
    ['eirmod', 'B'],
    ['tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.', ''],
];

$pdf = new TCPDF();
$pdf->setLeftMargin(26);
$pdf->setRightMargin(26);
$pdf->addPage();

foreach ($content as $item) {
    $tmp = $pdf->getFontStyle();
    $pdf->setFont('', $item[1]);
    $pdf->Write($pdf->getFontSizePt() / 2, $item[0]);
    $pdf->setFont('', $tmp);
}
$pdf->Output();

Result:

Expected result:

Basically, it boils down to the return ''; in line 6441. When I remove it, it appears to be working as expected, but I assume it is there for a reason.

I have a similar issue, but it doesn't require any text formatting at the end of the line. Text of a certain size will get up to the boundary of the max page width (less margins) and not trigger wrapping. All remaining text vanishes. Doing something to purposely trigger a word wrap, such as adding extra spaces, will fix the issue. Similarly, disabling line 6448 (6.7.5) solves the issue, but as @DerPapst says, it must be there for a reason and removing it may cause other issues.

This will reproduce the issue without any formatting changes. I think the formatting changes are potentially a red herring:

<?php
require_once(__DIR__.'/vendor/autoload.php');

$content = [
    ['Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmodx', ''],
    ['tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.', ''],
];

$pdf = new TCPDF();
$pdf->setLeftMargin(26);
$pdf->setRightMargin(26);
$pdf->addPage();

foreach ($content as $item) {
    $pdf->Write($pdf->getFontSizePt() / 2, $item[0]);
}

$pdf->Output();

You can change eirmodx to eirmodxl and it'll exhibit the same behavior. However, add enough characters and it forces a correct wrapping and the problem does not appear.

Exhibits the issue:

$content = [
    ['Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmodxl', ''],
    ['tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.', ''],
];

Does NOT exhibit the issue:

$content = [
    ['Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmodxll', ''],
    ['tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.', ''],
];

This seems like some sort of boundary edge case.

@williamdes @nicolaasuni possible to get someone to take a look and at least verify it is reproducible by others?
