1936361 - When pressing Ctrl+A then Left Arrow Key on a long text, the Text Cursor doesn't go to the first letter of the text

Status: NEW

(Core :: Layout: Form Controls, defect, P3)

Description

[Fernando M. Muniz]

Attachment: Ctrl+A then Left Arrow Key behaves incorrectly.

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:133.0) Gecko/20100101 Firefox/133.0

Steps to reproduce:

Pressed Ctrl+A then pressed the Left Arrow Key on a long text anywhere that only allows one line.

The text I pasted in the address' text entry box was:

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

Actual results:

The Text Cursor went to the first VISIBLE letter of the long text.
Right at "ut aliquip".

Expected results:

The Text Cursor should have gone to the actual first letter of the whole text entry box.
Right at "Lorem ipsum".

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I can reproduce the issue on Nightly135.0a1 ubuntu24.04.

Thanks for the bug report and reduced testcase! I can reproduce. I can't take a look right away but I'll take a look soon. [leaving needinfo open]

(I can confirm that this is Linux-specific, too; I can't reproduce on Windows or macOS. I see Alice0775 already flagged it as-such; thanks!)

The component has been changed since the backlog priority was decided, so we're resetting it.
