My formula bar contains a reference to a query (MyAsset in this example): Just a sample formula
I place the cursor before "MyAsset" and start typing (Table.B in this example): IntelliSense pops up as expected
Let's say Table.Buffer is exactly what I want and I press Tab to autocomplete. At this stage Table.Buffer overwrites MyAsset too: Pressing Tab upon IntelliSense's suggestion overwrites what was to the right of the cursor
Clearly I expect "My Asset" to stay, and it would be great if an opening parenthesis were added to be in line with DAX formula bar IntelliSense.
In general, when I press Tab after IntelliSense's suggestion, I expect it to work in the same way as autocomplete works in DAX formula bar: it should autocomplete the function name and add an opening parenthesis, if it's relevant for the item at hand. In this case, it should have been Table.Buffer(MyAsset instead of Table.Buffer only.
