minor update-lack on style change in EditDialog

[horst-p-w-neubauer]

Details for the issue

when you change style and EditDialog Value is null it doesn’t change

when EditDialog Value isn’t null, it works fine

after swapping to table (filled) and back to empty SQL-Tab everthing is fine)

works both ways the same: dark to light and light to dark

Same if you browse a table, click into a cell - EditDock shows cell-data, change main tab to pragmas and change to/from dark style - EditDock is not gonna be refreshed immediately.

I had a lot of problems reapplying settings to the QScintilla widget. Either it is broken or I don't understand the logic.

@mgrojo , I think there are different minor refresh issues related to the EditDock and, sorry, I don't realy think its the widget itself.
If I add
editDock->setCurrentIndex(QModelIndex());
after
editDock->reloadSettings();
in void MainWindow::reloadSettings()
it works - but thats probably only an workarround - not a solution.

What I don't understand: When I select a cell in the Data Browser - than switch to Strucutre Tab - the EditDialog is allready showing the last selected value - switching back to the Data Browser it changes to a value, that is not realy inside the selected table.

I'm not 100% sure I can follow you because on your screenshots you don't show the cells you click. But here's what I think I understood:

• Click any cell with NULL value -> the Edit dialog shows "NULL" in the line number area of the text editor
• Click a cell with an empty string value -> the Edit dialog still shows "NULL" in the line number area

This issue should be solved with the latest commit. Can you double check it's working and confirm that's the issue you meant 😄 Do you know if this issue already existed in version 3.11.2?
