I’m having a similar problem on Chrome OS with the same Bedrock version. Specifically the chat window is acting strange with the keyboard now. I’m primarily broken when trying to use auto-complete using the Tab key.
Steps:
Launch Minecraft Bedrock v26.51 from Google Playstore on ChromeOS.
Open a local vanilla world with cheats enabled.
Open chat and enter /gam.
Press the physical Tab key.
Observed: /gamō is inserted into the chat field.
Expected: Tab completes or cycles through command suggestions.
Note: I can still perform auto-complete by using the DPad-Right button on my controller.
Related, the cursor is not always going to the end of the text window.
Steps:
Launch Minecraft Bedrock v26.51 from Google Playstore on ChromeOS.
Open a local vanilla world with cheats enabled.
Open chat and enter /.
Observed: The cursor is now before the /.
Expected: The cursor is after the /.
