Steps to reproduce the problem:
1. Use an external Bluetooth keyboard. (Spanish locale)
2. Go to a web and find a text box.
3. Try to type any accented character such as á, é, í, ó, ú.

What is the expected behavior?
The accented character is entered.

What went wrong?
Instead of the accented character, the character composition doesn't happen. The accent gets inserted on its own and then the expected vowel: ’a

Did this work before? Yes Don't know. Several months ago it worked.

Chrome version: 55.0.2883.91  Channel: stable
OS Version:

This happens on my mother's tablet with Android 6. It isn't an issue with the keyboard, as entering accented characters in any other application works just fine. As it is not my device, I don't know the exact moment in which it stopped working. The last Chrome update changed the behaviour, previously the composition got stuck (after typing the first accented character all characters were accented, even consonants).
