Gantt enablePersistence="true" will cause issue if enableVirtualization="true"

  • Details about the bug.
    The bug happens when we add enablePersistence="true" in a code where enableVirtualization="true"

  • Reproducing steps.

    Download https://drive.google.com/file/d/19z2pVkIQL_Bb6rK4XE7ZdiH9FK40wYty/view?usp=sharing, extract it, open the gantt-persistence-bug folder in a terminal, run `yarn` command, run `quasar dev`, then it will open a tab in browser: http://localhost:8081/#/ . The bug should be immediately showing

  • Screenshots, code snippets, and stack traces, if applicable.

  • Working sample if possible, which will help us provide a solution sooner.
    I have already provided it in "Reproducing steps" section. For additional info, the sample contains a git repo. The currently selected branch is `gantt-persistence-bug` branch. There is also a `develop` branch where the bug doesn't happen because I set enablePersistence="false". Also another branch `gantt-persistence-bug-hacky-fix` where I hackily fix the bug by checking a variable first before setting it. But the hacky fix still can't make the persistence feature works. For example, if we hide/show the column and then refresh the browser, the change doesn't persist
