Bisected to r275860 "Enable DirectWrite by default"
Landed in 37.0.2043.0

Confirmed by disabling DirectWrite and observing correct rendering.
Note, the official Chrome can't disable it anymore.

Thanks for filing the issue!

Able to reproduce the issue on reported chrome version 71.0.3578.98 and on the latest  canary 73.0.3664.0 using Windows 10.
Note: Issue isn't seen on Mac 10.14.1 and Ubuntu 14.04

As the issue is seen from M60(60.0.3112.0) considering it as Non-Regression and marking it as Untriaged.
From C#2, CC'ing scottmg@ for further inputs.

The page uses a hard-coded width that makes assumptions about the text rendering mode. This never worked other than under very specific circumstances on a specific platform with specific settings. This is broken on linux, macos, chrome, and android on all chrome versions. 

Hard-coding pixel values like this for text is not a good idea.

#4 - but it uses white-space: pre-wrap, which means it should wrap, or am I missing something?
Ellipsizing the first line makes no sense in this scenario...

To give a little background:

This is based on a generated report.  The size of the various elements are defined as a template which is repeated for a data set.  Although my example does not set a height, there was a specific height set which easily can hold this amount of text.

I would think the proper behavior is that text in the div should show as much as possible, wrapping, and finally ellipsizing at the very end if the text can't fit.  The fact that this happens only with a specific text alignment, and in the middle of the text, is bizarre.
