[Bug] Form builder field wrappers grow infinitely (width feedback loop) on Craft 5

[Alice-zhan000]

What happened?

On Craft 5, opening any form in the Freeform form builder causes every field's
drag wrapper (div[draggable="true"] with the sc-gnWmTK styled-component
class) to receive a massive inline width value that keeps growing on every
reflow. The inner [data-field-type] element is fine — the bug is on the drag
wrapper above it.

Result: fields stretch tens of thousands of pixels horizontally. Selecting or
editing a field becomes impossible.

Expected Behaviour

Drag wrappers should match the row width (or be auto), as they did on
Craft 4.

Actual Behaviour

Drag wrappers get assigned an inline pixel width that grows on every reflow.

DOM Snippet

Trimmed DOM of a single row

<div class="sc-fWJabs bJeSsJ">
  <div class="sc-dkrmZR jxmDlE" style="transform: none;">
    <div class="sc-dBEzSj bfjFjk"
         style="opacity: 0; width: 37842.7px; transform: translate3d(0px, 0px, 0px) scale(0);">
    </div>
    <div class="sc-gnWmTK kkxAPD" draggable="true"
         style="width: 37846px; opacity: 1; transform: none;">
      <button>…</button>
      <button>…</button>
      <div data-field-type="text" class="sc-loChfy eBHEAE field">…</div>
    </div>
  </div>
</div>

### Errors and Stack Trace (if available)

```shell

How can we reproduce this?

1. Use Craft 5.10.x + Freeform 5.15.13.
2. Edit any existing form (a mix of text, textarea, dropdown, email, cards fields, etc.).
3. Open the form builder.
4. Inspect any field's drag wrapper — it has an inline style="width: 18923px"` (or similar).
5. Trigger a reflow (resize window, scroll, click) — the width value increases each time.
