SWT Browser loads IE instead of Edge from SWT version 3.129.0 – Sidebar not compatible with IE

[glasedom]

After updating to SWT 3.129.0 or later, the sidebar is loaded in the internal browser using Internet Explorer (IE), but the sidebar is not IE-compatible. The reason is the use of SWT.DEFAULT as the style in the Browser constructor. The SWT.DEFAULT is not a valid style for the Browser widget. This should be changed to SWT.NONE or SWT.EDGE instead of SWT.DEFAULT.

Steps to reproduce:
Clone the acrolinx-sidebar-demo-java.
Update SWT to version 3.129.0.
Run the SWT demo.
Check the sidebar.

Same problem here:

The switch from previous Eclipse SWT plugin version (org.eclipse.swt.win32.win32.x86_64) from
3.128.0.v20241113-2009
to
3.129.0.v20250221-1734
does have a switch in the logic when instantiating an SWT Browser instance.
Acrolinx simply pass -1 for the browser style here, which has the meaning that all bits are set (I do not know why...). Normally we have to pass zero to use a default browser.

• In the old SWT version (Eclipse 4.34), an Edge browser is used if specfic flag for it is passed (Bit 18), otherwise an IE browser is instantiated: IE is the default browser!

• In the new SWT version (Eclipse 4.35+), an IE browser is used if specific flag for it is passed, otherwise Edge browser is instantied: Edge is the default browser!
