TrackChanges: SpellCheck-replacement with wrong DEL-Tag

problem:

(tested on Ubuntu in Firefox and Chrome: )

• example: "Apache 2.x auf Unix-Systemen" (eg in simple-en-de.zip)
• add another "auf": "Apache 2.x auf <INS>auf </INS>Unix-Systemen" -> the SpellChecker marks "auf auf" as error and a right click suggests to use "auf" instead.
• left-click on the suggested "auf" -> result is:
  "Apache 2.x auf<DEL>auf</DEL> Unix-Systemen"
• BUT result should be (the second "auf" should be removed!):
  "Apache 2.x auf Unix-Systemen"

(see also: https://jira.translate5.net/browse/TRANSLATE-1605)

answer:

This mechanism is perfectly right according to the Search&Replace-algorithm.

• First, the existing content is removed (= the first "auf" is marked as deleted, the second "auf" is being removed):
  "auf1 <INS>auf2</INS>" -> "<DEL>auf1</DEL>"
• Then, the replacement ("auf3") is inserted at the beginning of the range:
  "<DEL>auf1</DEL>" -> "<INS>auf3</INS><DEL>auf1</DEL>"

The result "only looks wrong" in this case because the content of the replacement is the same.
