1658927 - IME popup is incorrectly positioned with desktop APZ zooming

Status: RESOLVED FIXED

(Core :: Panning and Zooming, defect, P3)

Description

[Kartikaya Gupta (email:[e-mail])]

Reproduced on macOS using these STR:

• Go to macOS system settings -> Keyboard -> Input Sources tab, and add Japanese using the "+" button under the left pane. I didn't change any of the defaults that show up in the right pane, but make sure the "Show input menu in menu bar" option is checked.
• Go to a page with an input field, e.g. https://staktrace.com/kats/contact.php and zoom in using a pinch gesture on the macOS trackpad
• Put focus in the input field
• Use the input switcher in the macOS menu bar to switch to "Hiragana"
• Type the letter "a"
• Observe the location of the IME popup that shows up

Expected:

• Is near the cursor

Actual:

• Is floating some distance away. Exact position depends on how much you've zoomed and such

Applying the layout-to-visual transform to these rects seems to fix the problem.
