Neither Ctrl+Alt+Shift keyboard shortcuts work if Alt+Shift is bound to keyboard layout switch

On Ubuntu 18.04 with GNOME triple shortcut combinations (like Ctrl+Alt+Shift+key) are always treated like Ctrl+Shift+key, so Alt is skipped. However, all double combinations (with Ctrl+Shift+, Ctrl+Alt+, Alt+Shift+) are processed properly in all windows.

This happens if the Alt+Shift combination is bound to switch keyboard layout (using gnome-tweaks, as described here 18.04 ctrl+shift to change language)

Examples from Intellij IDEA:

• Ctrl+Alt+Shift+S: expected Project Structure, but nothing happens (not sure what Ctrl+Shift+S makes by default)
• Ctrl+Alt+Shift+R: expected Resolve conflicts, actually: Replace in Path is called

Note:

• opposite to the issue described in 18.04 ctrl+shift to change language and bug 1683383 this trouble appears as wrong shortcut is used (Alt key is ignored) rather than unexpected layout switching
• The problem happens in any window, not only Intellij IDEA
• The problem happens with any key, which includes Ctrl+Alt+Shift+

So, is it a bug that should be reported to Ubuntu / GNOME / Tweaks developers? Or am I misusing something?
