Screenrecord of the bug

SUMMARY
When live preview of the pdf is enabled using PDFLaTeX, you cannot see the cursor on the pdf a second time if the cursor on the editor is on the same line as the previous request of this feature. If you change line between the two requests, the feature works correctly. 

STEPS TO REPRODUCE
0. Enable live preview of the pdf 
1. Select a line on the editor
2. Click the button to show the cursor position on the pdf
3. Scroll on the pdf using the mouse
4. Select the same line on the editor
5. Click the button to show the cursor position on the pdf

OBSERVED RESULT
The first time, after step 2, the pdf moves to the cursor position. The second time, after step 5, the pdf doesn't move at all. 

EXPECTED RESULT
Each time the pdf moves to the cursor position.
