Different autocompletion results

[GerdP]

What steps will reproduce the problem?

I've noted this while mapping gas pipelines. I use either a preset or the standard add tag Dialog for this.
Reproduced with empty JOSM directory.

1. Create empty data layer and add 6 new nodes with the tags marker=post + utility=gas
2. Select 1st node and add tag operator "Exxon Mobil" (with blank)
3. Select 2nd node and add tag operator="EWE"
4. Select 3nd node and add tag operator="ExxonMobil" (no blank)
5. Select 4th node and add tag operator="Gasunie"
6. Select 5th node and add tag operator="Ex", note that autocompletion selects "ExxonMobil"
7. Select 6th node and use preset Man Made/Pipeline/Marker and type "Ex" in the operator field

What is the expected result?

Both steps 5 and 6 should result in operator "ExxonMobil" as this was the last value that I typed starting with these characters.

What happens instead?

It seems the preset always selects the value "Exxon Mobil" with blank and I have to manually remove the blank.

Please provide any additional information below. Attach a screenshot if possible.

Not sure if this is intended behaviour? Didn't look at the code yet.
