Bug Description

Reproduction steps

I have gotten this with several different Regex expressions, so I'm not sure if it is particular to the expression, but this expression has been triggering it a lot today: ^\t*Assert\.AreEqual\((("[^"]*")|([^,\(\n\r]+(\([^\)\n\r)]*\),?)?)),\w*((\n\r)*\s*)(("[^"]*")|([^,\(\n\r]+(\([^\)\n\r)]*\),?)?)+)(,|\)) along with this test string:

                Assert.AreEqual("Azeri",
                    my.frog(ate, an(old), apple)),
                    "Setup problem: AzeriJUD should return language name as Azeri.");
                Assert.AreEqual("Engl, ish",
                    ReferenceTextTestUtils.CreateCustomReferenceText(persistenceImpl, TestReferenceTextResource.EnglishJUD));
                Assert.AreEqual(my.frog,
                    ReferenceTextTestUtils.CreateCustomReferenceText(persistenceImpl, TestReferenceTextResource.EnglishJUD),
                    "Setup problem: AzeriJUD should return language name as Azeri.");
                Assert.AreEqual(my.frog(ate, an),
                    ReferenceTextTestUtils.CreateCustomReferenceText(persistenceImpl, TestReferenceTextResource.EnglishJUD),
                    "Setup problem: AzeriJUD should return language name as Azeri.");
                Assert.AreEqual(my.frog(ate, an(old), apple),
                    ReferenceTextTestUtils.CreateCustomReferenceText(persistenceImpl, TestReferenceTextResource.EnglishJUD),
                    "Setup problem: AzeriJUD should return language name as Azeri.");
                    "Setup problem: AzeriJUD should return language name as Azeri.");
                Assert.AreEqual("Engl, is, ()h", mom);

                Assert.AreEqual(my.frog(), ReferenceTextTestUtils.CreateCustomReferenceText(persistenceImpl, TestReferenceTextResource.EnglishJUD), "Setup problem: AzeriJUD should return language name as Azeri.");

I think every time it crashes, it happens when I am editing the expression, but it might also have happened when editing the test data. It is often (but maybe not always) preceded by edits that result in a "Catastrophic backtracking" message

Expected Outcome

Don't crash.

Can you reproduce this in an incognito window? I suspect this may be caused by a rogue browser extension.

So far unable to repro in an incognito window, so perhaps you're correct.
