test case

+++ This bug was initially created as a clone of Bug #99264 +++

This *may* be a dup, but:
* I cannot reproduce the problem from the opening report of bug 99264 in the Gtk port.
* Regarding the test case I'm attaching, the text isn't wrong; it's not visible.
  - 100% reproducible on the Gtk port of two systems
  - 0% reproducible in Chromium (from package) on the same two systems
  - 0% reproducible in the Mac port

Steps to reproduce:
1. Launch GtkLauncher and do NOT resize the window
2. View the attached test case
3. While viewing the test case, use the mouse to slowly resize the window

Expected results: At steps 2 and 3, "iWork" would appear on every line.

Actual results: At step 2, "iW" appears on every line. At step 3, the "ork" instances pop in and out of view.

As you may have guessed, the real-world test case is icloud.com. When viewing that site in Epiphany, I can make the "ork" as well as "eminders" blink in and out of existence by Ctrl+=, Ctrl+-, and window resizing.
