Subject: [FIX] web: properly resize textarea when its value changes

Before this commit, a textarea would not resize when its value changed if the event was different than "input" or "focus".

This commit fixes it by also listening to the "change" event, and by triggering it at appropriate times.

PR: #26430
Task: 1869469
