Fixes #11454

Other components needing the same fix are ListSelect,NativeSelect,Combobox (The ones implementing HasDataProvider and extending AbstractSingleSelect. Grid is not affected as it extends AbstractListing and hadles selection differently)

Fixes #11489

If you use multiple UIs, the use of SLF4J would depend on the UI initialization order which could be pretty random. If you have multiple servlets, it's even better to init SLF4J in ServletContextListener.

Fixes #11502

Documents the possibility to use vaadin:// and theme:// in JavaScript and StyleSheet annotations.

Fixes #8675

Add DataChangeHandler removal in v7 Grid just as in v8 Grid.
Adding tests to the fix to verify, that NPE is not thrown.

Add check for the V8 TextField used in Table in compatibility mode. This makes clicking cell with the TextField select the row, preserving behaviour from V7.
Through, as it's noted also before, this is an improved workaround, not a proper solution to address the issue.

Fixes #11474

Removed link to and recommendation  for SQLContainer

Make improve of caching for hierarchical data optional

Fixes #11477

If BrowserWindowOpener is used with constructor using Class<? extends UI> as parameter, it will have UI provider with generated url. This will not match UI beans in contextual storage and hence newly created UI will not be managed bean. Due this, injection to new UI instance will not happen. If you are using CDI , BrowserWindowOpener(String) constructor needs to be used.

Fix example of using grid.setStyleGenerator in one line

Explicitly reset the value in case if it was cleared.
Ignore the case for selecting a suggestion.

Fixes vaadin/testbench#1122

* Add Test file

* Remove redundant check for for Firefox

It seems that in older versions of Firefox (at least, older than 45) the KeyPress event should be used instead of KeyDownHandler. At some point (works already on 58 version, the current one is 65) the issue was resolved and starting from Firefox 65 this hook prevents from navigating in the pop-up via keyboard.
Simply removing additional logic makes navigating in both DateField and InlineDateField possible

Fixes #11465

Checking that no prior Combobox behavior is broken

* Cleaning-up the code

Adding UI test

This fix was already applied to com.vaadin.client.ui.VCheckBox but the committer forget to apply the same fix to the com.vaadin.v7.client.ui.VCheckBox. Some people are still temporarely using the checkbox from the compatibility package.

Fixes #11451

* Fix an NPE caused by the previous fix to Grid's frozen columns (#10653)

If the user managed to get two frozen column count changes into a single server round-trip before the component had been attached, the previous fix  #11346 lead to a null pointer exception since there was no diff state available.

This fix adds a null check before removing the frozen column count value from the diff state so that this will not happen.

Closes #10653

Clear contents of iframe clone that is in a Window so that when it's reattached to DOM we don't get 404
