+# This test is checking to ensure that if a section is removed in the presence
+# of a segment that the segment maintains its shape and properties and that any
+# section inside that segment maintains the relative positioning it had in the
+# segment. Note worthy is that .text3 keeps its offset despite it being
+# possible to place it after .text when .text2 is removed.
