Inccorect display when Gradient editor is over 2048 pixels.

Environment/Versions

• GIMP version: 2.10.32
• Package: Self-compiled
• Operating System: Linux

Description of the bug

This is what the gradient should look like:

This is what it looks like when the window is widened:

Anchors are space appropriately but the width of the gradient itself is limited (and no longer matches the anchors) Coincidentally the part that represents the actual span of the gradient is 2048px wide.

Reproduction

Is the bug reproducible? Always

Reproduction steps:

1. Open gradient editor
2. And a sufficiently wide display, widen the window to well over 2000 pixels

…

Expected result: gradient display is widened

Actual result: gradient display is limited to 2048px.

Additional information

Reported against 2.10.32 because I haven't compiled 2.10.34 yet. Easy enough to check that the problem still exists n 2.10.34 (I can't find a bug about this, open or closed).

Problem is not related to the number of anchors in the gradient (same problem with a much lower count).
