Text fields don't scroll while selecting text with Shift

This is still a problematic bug to going into 1.14 release. I understand that most hardened creators may not come across this issue working with functions or pasting everything into command blocks but some of us like to again select text in game larger than the visible text box.

I would like to provide information on the "command block" part of this bug:

The bug

When selecting text in a command block the text does not scroll.

How to reproduce

Try to make a selection of text (with Shift+Arrows) in a command block on a long command that goes beyond the frame.

Example

• Here is what is excepted:

• Here is what is happening now in 1.14:

Note

This bug does not occur in 1.13, 1.13.1, 1.13.2 and earlier versions. It is only a problem in 1.14. Before, everything worked fine.

This bug is really annoying for map creators so please, fix this bug before the official release of 1.14!

Still in 1.14 Release! It is very bad for map creators! Especially that the bug does not have to be hard to fix...

I want to make sure that, when you fix this bug, also look at this one. Both are related to text field and Shift key.

Still in 1.14.1 Release

Still in 1.14.2 Pre-Release 1 and 1.14.2 Pre-Release 2

1.14.2 pre4

Confirmed for 1.14.3-pre4

Still in 1.14.3. Is very annoying. Please fix soon.

Also present in every 1.14.4 snapshot to date

Confirmed for 19w34a.

Also may I add that, MC-155958 is a duplicate of MC-121772. It has nothing to do with this bug.

Confirmed for 19w35a.

Confirmed for 19w36a.

Still in latest snapshot to date; being 19w37a
Next snapshot really needs to focus on UI fixes, no matter if they are low priority issues.
This is particularly annnoying, that is all.

19w40a

Confirmed for 19w41a.

In 1.15.1 there is the same bug...

I'm not sure but maybe when Workflow changed from Global Mojang to Java, this bug's assigned priority got lost? Can't find it on Details.

Every time I do anything on minecraft with commands this bug annoys me. Every. Single. Time. Pleeeeeease fix asap.

can we just mention how a 16-month old bug with 45 votes hasn't even been assigned a priority by Mojang yet? I love your work, but this is beginning to suggest incompetence as a company.

Confirmed for 1.16-pre4

This happens when you scroll to the left too

Oh god, please FIX IT already! This is so annoying small bug and it takes Mojang years to fix it, like every single thing they break in their game. The game literally consists of billion small bugs, that they even had right in the game in the old better versions, but they broke it.

Can confirm in 1.17 Pre-release 4.

Can confirm in 1.17 and 1.17.1 Pre-release 1.

Code analysis based on Minecraft 1.17.1 with yarn mappings.

Note that selectionEnd is where the selection initially started, and selectionStart is where the cursor currently is. Since selectionEnd doesn't change when highlighting text, it is not updated:

net.minecraft.client.gui.widget.TextFieldWidget#setCursor(int)

this.setSelectionStart(cursor); // Move the cursor
if (!this.selecting) {
    this.setSelectionEnd(this.selectionStart); // selectionEnd does not need to be updated when selecting
}
...

The problem is that the scrolling logic is handled in setSelectionEnd, so it is skipped while selecting.

To fix this, the scrolling code should be moved to a separate method, and it should be invoked in setCursor even when selecting.
