Could be related, but looks like the issue below was fixed in the v3.4.10.

With v3.4.9 the code <input :maxlength="undefined" /> also causes the hydration issue

[Vue warn]: Hydration attribute mismatch on <input value>​ 
  - rendered on server: maxlength="undefined"
  - expected on client: maxlength=""

@Ky6uk thanks, updated the issue and indeed, the disabled part is gone but draggable is still causing a hydration error.

@manniL yeah, and I can confirm that mine one was just fixed in the v3.4.10 a couple of hours ago 😅
