Think about:
What exciting things did you accomplish?
What loose ends remain?
Big questions? Big ideas?

• File dialog scrunches / truncates file names

  • The file dialog comes from @jupyterlab/filebrowser
  • It's the same as the file browser on the left panel
    • The file browser on the left panel works perfectly!
  • We're just using in a different context to display it as a modal
    • Maybe the context is the problem, and the file browser in the left panel depends on some CSS from a parent element to look correct?
  • Reproduction is inconsistent
    • Some people/browsers see ellipses, some people don't
      • Sanjay sees ellipses in Firefox, no ellipses in Chrome
    • Some people see truncation, some people don't
      • It doesn't seem like truncation depends on the browser
    • It seems to have nothing to do with browser model or browser version
      • Matt (Ubuntu) was using Firefox 137, and it reproduced
      • Kristin (Mac) was using Firefox 138, and it did not reproduce
      • Matt upgraded to Firefox 138, and it did reproduce
      • Martin (Fedora) was using latest Firefox, and it did not reproduce
      • Sanjay (Mac) reproduced in Chrome & Firefox 137
      • Arjun (Mac) was using Chrome, unable to reproduce fully
        • Decreasing width of the file browser hides modified dates
        • But the filenames never get scrunched
      • Felipe (Mac) was using Safari & Firefox, and it reproduced
  • Fiddling around with styles sometimes helps, but hasn't yet yielded a full solution where the dialog works exactly like the file browser in the left panel.
    • TODO: Sanjay to fill out some of the things he's tried!
  • DID SANJAY ('s drunk AI companion) FIX IT ?!?!?!?!?!
    • How? … TODO …
      • Sanjay modified packages/base/source/style/dialog.css
        • In the main branch, there's basically nothing in that file

• Were able to fix

  :
  • Symbology panel: color steps are not recovered properly after setting graduated radius - https://github.com/geojupyter/jupytergis/issues/694 with https://github.com/geojupyter/jupytergis/pull/700
