Chrome Version: 70.0.3532.0

What steps will reproduce the problem?
(1) Install Array input method (traditional Chinese)
(2) Ctrl-Shift-Space to use it 
(3) Type t
(4) Hit space bar

What is the expected result?
(3) Candidate window shows 10 glyphs
(4) The glyph 的 is used

What happens instead?
(3) Depending on version, some times only 5 glyphs are shown (very wrong), other times 11 glyphs are shown (also very wrong)
(4) The first glyph 隨 is used

Array input method has this corner case but it is the most used word in Chinese. All other platforms implement this correctly (Windows/Mac/Linux/Android).
