Hi,

Since it was a one liner I kept description to a minimum. On the PR checks

• I do not believe there is a test matching this scenario
• On screenshots, this change prevent the opening of the keyboard as seen in #26577
• No change on the accessibility part

As long as there is no conflict I intended to rebase the branch after feedbacks. Do you need any other information ?
