Here it is the example code:

(true ? 0 
    : 1);

The highlight is ok (figure1.png).

After adding space symbol before bracket at the first line highlight is broken(figure2.png). After changing window focus or carriage position (move carriage to position after opening bracket and then back to position before opening bracket(for 2 times, sic!) or to the line above ternary operator) highlight becomes normal again.
