Hi thanks for the work, after a second look I notice that the unit tests are failing. The end offset is not calculated correctly according to these tests. Some more work will need to be done to find a fix. Unfortunately we can not merge it with the unit tests failing.

Hi Aiday, I checked the failing test case, found the token endIndex is 30, it's also the last column of a line. I think inline decoration's endOffset shouldn't be greater than line's last column, should we update the failing test case? Please check.

Hi thanks for the reply. @hediet I noticed you made some changes previously on the test code that this PR aims to change. If it wasn't you who wrote that specific test let me know. Do you think it would be okay to make the change proposed by @yshaojun?

@yshaojun thanks for fixing this!
